JAVA ENHANCEMENT PROPOSALS (JEP):
JEP 305: Pattern Matching for instanceof (Preview)
Enhance the Java programming language with _pattern matching_ for the `instanceof` operator.
[Pattern matching](http://cr.openjdk.java.net/~briangoetz/amber/pattern-match.html) allows common
logic in a program, namely the conditional extraction of components from objects, to be expressed
more concisely and safely. This is a [preview language feature](http://openjdk.java.net/jeps/12) in
JDK 14.
JEP 343: Packaging Tool (Incubator)
Create a tool for packaging self-contained Java applications.
JEP 345: NUMA-Aware Memory Allocation for G1
Improve G1 performance on large machines by implementing NUMA-aware memory allocation.
JEP 349: JFR Event Streaming
Expose JDK Flight Recorder data for continuous monitoring.
JEP 352: Non-Volatile Mapped Byte Buffers
Add new JDK-specific file mapping modes so that the `FileChannel` API can be used to create
`MappedByteBuffer` instances that refer to non-volatile memory.
JEP 358: Helpful NullPointerExceptions
Improve the usability of `NullPointerException`s generated by the JVM by describing precisely which
variable was `null`.
JEP 359: Records (Preview)
Enhance the Java programming language with [records][records]. Records provide a compact syntax for
declaring classes which are transparent holders for shallowly immutable data. This is a [preview
language feature](http://openjdk.java.net/jeps/12) in JDK 14.
JEP 361: Switch Expressions
Extend `switch` so it can be used as either a statement or an expression, and so that both forms can
use either traditional `case ... :` labels (with fall through) or new `case ... ->` labels (with no
fall through), with a further new statement for yielding a value from a `switch` expression. These
changes will simplify everyday coding, and prepare the way for the use of pattern matching in
`switch`. This was a [preview language feature](http://openjdk.java.net/jeps/12) in [JDK
12](https://openjdk.java.net/jeps/325) and [JDK 13](https://openjdk.java.net/jeps/354).
JEP 362: Deprecate the Solaris and SPARC Ports
Deprecate the Solaris/SPARC, Solaris/x64, and Linux/SPARC ports, with the intent to remove them in a
future release.
JEP 363: Remove the Concurrent Mark Sweep (CMS) Garbage Collector
Remove the Concurrent Mark Sweep (CMS) garbage collector.
JEP 364: ZGC on macOS (Experimental)
Port the ZGC garbage collector to macOS.
JEP 365: ZGC on Windows (Experimental)
Port the ZGC garbage collector to Windows.
JEP 366: Deprecate the ParallelScavenge + SerialOld GC Combination
Deprecate the combination of the Parallel Scavenge and Serial Old garbage collection algorithms.
JEP 367: Remove the Pack200 Tools and API
Remove the `pack200` and `unpack200` tools, and the `Pack200` API in the `java.util.jar` package.
These tools and API were [deprecated for removal in Java SE 11](http://openjdk.java.net/jeps/336)
with the express intent to remove them in a future release.
JEP 368: Text Blocks (Second Preview)
Add _text blocks_ to the Java language. A text block is a multi-line string literal that avoids the
need for most escape sequences, automatically formats the string in a predictable way, and gives the
developer control over the format when desired. This is a [preview language
feature](http://openjdk.java.net/jeps/12) in JDK 14.
JEP 370: Foreign-Memory Access API (Incubator)
Introduce an API to allow Java programs to safely and efficiently access foreign memory outside of
the Java heap.
RELEASE NOTES:
xml/javax.xml.transform:
JDK-8228854: Default ErrorListener No Longer Reports Warnings and Errors to the Console
Prior to this release, the `javax.xml.transform.ErrorListener` specification defined that the
default `ErrorListener` implementation reported warnings and errors to `System.err`, and
`System.out` in some cases. This requirement has been removed as of this release and the
default `ErrorListener` now takes no action for warnings and recoverable errors; and in the
case of a severe error, throws a `TransformerException`.
It is recommended that applications always register their own `ErrorListener` to ensure proper
handling of warnings and errors.
tools/javac:
JDK-8234211: Allow Discoverable javac Plugins to be Invoked by Default
javac "plugins" can now opt-in to be started by default if not started explicitly in the
options passed to `javac` from the command-line or in the `options` argument of an API
invocation. This behavior is enabled by implementing the method `Plugin.isDefault()` to
return `true`.
JDK-8164819: toString() on Annotation Objects is Consistent Between Core Reflection and javac
Both core reflection and `javac`, through annotation processing, have objects representing
annotations. The `toString` output for the two kinds of annotation objects now follow the same
conventions. These conventions allow the output to be used in source code.
deploy:
JDK-8222563: Removal of netscape.javascript.JSObject::getWindow Method
The obsolete `netscape.javascript.JSObject::getWindow` method has been removed. This method
was deprecated in JDK 9. As of JDK 11, there is no longer a useful way to use this method; it
always returns `null`.
core-libs/java.net:
JDK-8233296: Behavior of MulticastSocket getOption/setOption for IP_MULTICAST_LOOP Conforms With the StandardSocketOptions.IP_MULTICAST_LOOP Specification
The `MulticastSocket` methods `getOption` and `setOption` have been changed to conform to the
behavior described in the `StandardSocketOptions.IP_MULTICAST_LOOP` specification.
`MulticastSocket.getOption(StandardSocketOptions.IP_MULTICAST_LOOP)` now returns true if
loopback mode is enabled. Setting
`MulticastSocket.setOption(StandardSocketOptions.IP_MULTICAST_LOOP, true)` enables loopback
mode.
JDK-8225499: InetSocketAddress.toString Format Changes for IPv6 Literals and Unresolved Addresses
The method `InetSocketAddress::toString` has been improved regarding the handling of IPv6
addresses. The implementation now encloses the IPv6 literal in brackets, which adheres to the
specification outlined in RFC2732.
Additionally, the string format for unresolved addresses has been changed. The method now
represents the literal IP address with the token ``, for example:
`foo/:80` instead of `foo:80`. This is based on `InetAddress::toString`, which
returns a string of the form "hostname / literal IP address". To retrieve a string
representation of the hostname, or the string form of the address if it doesn't have a
hostname, use `InetSocketAddress::getHostString`, rather than parsing the string
representation.
JDK-8233141: DatagramSocket.send and MulticastSocket.send Throw IllegalArgumentException When Socket Is Not Connected and Packet Doesn't Contain Address
The `send` methods defined by `DatagramSocket` and `MulticastSocket` have been changed to
throw an `IllegalArgumentException` if the socket is not connected and the `DatagramPacket`
doesn't have a socket address. Prior to this change, these methods threw a
`NullPointerException`.
JDK-8233307: MulticastSocket getOption(IP_MULTICAST_IF) Returns null when outgoing interface not set
The `MulticastSocket` method `getOption` has been changed to conform to the behavior described
in `StandardSocketOptions.IP_MULTICAST_IF`.
`MulticastSocket.getOption(StandardSocketOptions.IP_MULTICAST_IF)` now returns `null` if no
interface has been set.
security-libs/javax.security:
JDK-8231196: DelegationPermission Allows Creating an Instance That Thows NPE on ::equals Call
When a `DelegationPermission` object is created and the `principals` argument does not contain
a pair of principals, an `IllegalArgumentException` is now thrown.
tools/javap:
JDK-8225748: javap Checksum Uses SHA-256
javap includes a checksum of the contents of the class file in verbose output. The checksum is
now calculated with the SHA-256 algorithm, instead of the older MD5 algorithm.
core-libs/java.util:i18n:
JDK-8222756: Plural Support in CompactNumberFormat
```java.text.CompactNumberFormat``` is now capable of dealing with plural forms. For example,
the number ```2,000,000``` is formatted to ```"2 Millionen"``` in ```LONG``` style, whereas
```1,000,000``` to ```"1 Million"``` in the German language.
JDK-8231273: Upgraded CLDR to v36
Locale data based on Unicode Consortium's CLDR has been upgraded to their version 36. For the
detailed locale data changes, please refer to the Unicode Consortium's CLDR release notes: -
[http://cldr.unicode.org/index/downloads/cldr-36](http://cldr.unicode.org/index/downloads/cldr-36)
core-libs/java.lang:
JDK-8205132: Thread.countStackFrames Changed to Unconditionally Throw UnsupportedOperationException
The terminally deprecated method `Thread.countStackFrames` has been changed in this release to
unconditionally throw `UnsupportedOperationException`.
This method will be removed in a future release.
JDK-8231602: Thread Suspend/Resume Are Deprecated for Removal
The following methods related to thread suspension in `java.lang.Thread` and
`java.lang.ThreadGroup` have been terminally deprecated in this release:
- `Thread.suspend()` - `Thread.resume()` - `ThreadGroup.suspend()` - `ThreadGroup.resume()` -
`ThreadGroup.allowThreadSuspension(boolean)`
These methods will be removed in a future release.
client-libs/2d:
JDK-8229800: Windows 2019 Core Server Is Not Supported
Windows Core Server 2019 does not ship a `dll` required by JDK in order to run. Specifically,
if a Java application, including a headless one, requires `awt.dll`, the Java runtime will
exit with an exception. There is no workaround. Until this is resolved, this Windows Server
configuration is not supported.
specification/language:
JDK-8231623: JEP 378: Text Blocks
Summary -------
Add _text blocks_ to the Java language. A text block is a multi-line string literal that
avoids the need for most escape sequences, automatically formats the string in a predictable
way, and gives the developer control over the format when desired.
History -------
Text blocks were proposed by [JEP 355](https://openjdk.java.net/jeps/355) in early 2019 as a
follow-on to explorations begun in [JEP 326](https://openjdk.java.net/jeps/326) (Raw String
Literals), which was initially targeted to JDK 12 but eventually [withdrawn and did not appear
in that release](https://mail.openjdk.java.net/pipermail/jdk-dev/2018-December/002402.html).
JEP 355 was [targeted to JDK 13 in June
2019](https://mail.openjdk.java.net/pipermail/jdk-dev/2019-June/003050.html) as a [preview
feature](http://openjdk.java.net/jeps/12). Feedback on JDK 13 suggested that text blocks
should be previewed again in JDK 14, with the addition of [two new escape
sequences](#New-escape-sequences). Consequently, [JEP 368](https://openjdk.java.net/jeps/368)
was [targeted to JDK 14 in November
2019](https://mail.openjdk.java.net/pipermail/jdk-dev/2019-November/003653.html) as a preview
feature. Feedback on JDK 14 suggested that text blocks were ready to become final and
permanent in JDK 15 with no further changes.
Goals -----
- Simplify the task of writing Java programs by making it easy to express strings that span
several lines of source code, while avoiding escape sequences in common cases.
- Enhance the readability of strings in Java programs that denote code written in non-Java
languages.
- Support migration from string literals by stipulating that any new construct can express the
same set of strings as a string literal, interpret the same escape sequences, and be
manipulated in the same ways as a string literal.
- Add escape sequences for managing explicit white space and newline control.
Non-Goals ---------
- It is not a goal to define a new reference type, distinct from `java.lang.String`, for the
strings expressed by any new construct.
- It is not a goal to define new operators, distinct from `+`, that take `String` operands.
- Text blocks do not directly support string interpolation. Interpolation may be considered in
a future JEP. In the meantime, the new instance method `String::formatted` aids in situations
where interpolation might be desired.
- Text blocks do not support raw strings, that is, strings whose characters are not processed
in any way.
Motivation ----------
In Java, embedding a snippet of HTML, XML, SQL, or JSON in a string literal `"..."` usually
requires significant editing with escapes and concatenation before the code containing the
snippet will compile. The snippet is often difficult to read and arduous to maintain.
More generally, the need to denote short, medium, and long blocks of text in a Java program is
near universal, whether the text is code from other programming languages, structured text
representing golden files, or messages in natural languages. On the one hand, the Java
language recognizes this need by allowing strings of unbounded size and content; on the other
hand, it embodies a design default that strings should be small enough to denote on a single
line of a source file (surrounded by " characters), and simple enough to escape easily. This
design default is at odds with the large number of Java programs where strings are too long to
fit comfortably on a single line.
Accordingly, it would improve both the readability and the writability of a broad class of
Java programs to have a linguistic mechanism for denoting strings more literally than a string
literal -- across multiple lines and without the visual clutter of escapes. In essence, a
two-dimensional block of text, rather than a one-dimensional sequence of characters.
Still, it is impossible to predict the role of every string in Java programs. Just because a
string spans multiple lines of source code does not mean that newline characters are desirable
in the string. One part of a program may be more readable when strings are laid out over
multiple lines, but the embedded newline characters may change the behavior of another part of
the program. Accordingly, it would be helpful if the developer had precise control over where
newlines appear, and, as a related matter, how much white space appears to the left and right
of the "block" of text.
### HTML example
_Using "one-dimensional" string literals_
``` String html = "\n" + " \n" + " Hello,
world
\n" + " \n" + "\n"; ```
_Using a "two-dimensional" block of text_
``` String html = """
Hello, world
"""; ```
### SQL example
_Using "one-dimensional" string literals_
``` String query = "SELECT \"EMP_ID\", \"LAST_NAME\" FROM \"EMPLOYEE_TB\"\n" +
"WHERE \"CITY\" = 'INDIANAPOLIS'\n" + "ORDER BY \"EMP_ID\", \"LAST_NAME\";\n";
```
_Using a "two-dimensional" block of text_
``` String query = """ SELECT "EMP_ID", "LAST_NAME" FROM "EMPLOYEE_TB"
WHERE "CITY" = 'INDIANAPOLIS' ORDER BY "EMP_ID", "LAST_NAME";
"""; ```
### Polyglot language example
_Using "one-dimensional" string literals_
``` ScriptEngine engine = new ScriptEngineManager().getEngineByName("js"); Object obj =
engine.eval("function hello() {\n" + " print('\"Hello,
world\"');\n" + "}\n" + "\n" +
"hello();\n"); ```
_Using a "two-dimensional" block of text_
``` ScriptEngine engine = new ScriptEngineManager().getEngineByName("js"); Object obj =
engine.eval(""" function hello() {
print('"Hello, world"'); }
hello(); """); ```
Description -----------
> _This section is identical to the same section in this JEP's predecessor, [JEP
355](https://openjdk.java.net/jeps/355), except for the addition of the subsection on [new
escape sequences](#New-escape-sequences)._
A _text block_ is a new kind of literal in the Java language. It may be used to denote a
string anywhere that a _[string
literal](https://docs.oracle.com/javase/specs/jls/se12/html/jls-3.html#jls-3.10.5)_ could
appear, but offers greater expressiveness and less accidental complexity.
A text block consists of zero or more content characters, enclosed by opening and closing
delimiters.
The _opening delimiter_ is a sequence of three double quote characters (`"""`) followed by
zero or more white spaces followed by a line terminator. The _content_ begins at the first
character after the line terminator of the opening delimiter.
The _closing delimiter_ is a sequence of three double quote characters. The content ends at
the last character before the first double quote of the closing delimiter.
The content may include double quote characters directly, unlike the characters in a string
literal. The use of `\"` in a text block is permitted, but not necessary or recommended. Fat
delimiters (`"""`) were chosen so that `"` characters could appear unescaped, and also to
visually distinguish a text block from a string literal.
The content may include line terminators directly, unlike the characters in a string literal.
The use of `\n` in a text block is permitted, but not necessary or recommended. For example,
the text block:
``` """ line 1 line 2 line 3 """ ```
is equivalent to the string literal:
``` "line 1\nline 2\nline 3\n" ```
or a concatenation of string literals:
``` "line 1\n" + "line 2\n" + "line 3\n" ```
If a line terminator is not required at the end of the string, then the closing delimiter can
be placed on the last line of content. For example, the text block:
``` """ line 1 line 2 line 3""" ```
is equivalent to the string literal:
``` "line 1\nline 2\nline 3" ```
A text block can denote the empty string, although this is not recommended because it needs
two lines of source code:
``` String empty = """ """; ```
Here are some examples of ill-formed text blocks:
``` String a = """"""; // no line terminator after opening delimiter String b = """ """; //
no line terminator after opening delimiter String c = """ "; // no closing
delimiter (text block continues to EOF) String d = """ abc \ def """;
// unescaped backslash (see below for escape processing) ```
### Compile-time processing
A text block is a [constant
expression](https://docs.oracle.com/javase/specs/jls/se12/html/jls-15.html#jls-15.28) of type
`String`, just like a string literal. However, unlike a string literal, the content of a text
block is processed by the Java compiler in three distinct steps:
1. Line terminators in the content are translated to LF (`\u000A`). The purpose of this
translation is to follow the principle of least surprise when moving Java source code across
platforms.
2. Incidental white space surrounding the content, introduced to match the indentation of Java
source code, is removed.
3. Escape sequences in the content are interpreted. Performing interpretation as the final
step means developers can write escape sequences such as `\n` without them being modified or
deleted by earlier steps.
The processed content is recorded in the `class` file as a `CONSTANT_String_info` entry in the
constant pool, just like the characters of a string literal. The `class` file does not record
whether a `CONSTANT_String_info` entry was derived from a text block or a string literal.
At run time, a text block is evaluated to an instance of `String`, just like a string literal.
Instances of `String` that are derived from text blocks are indistinguishable from instances
derived from string literals. Two text blocks with the same processed content will refer to
the same instance of `String` due to
[interning](https://docs.oracle.com/javase/specs/jvms/se12/html/jvms-5.html#jvms-5.1-300), just
like for [string
literals](https://docs.oracle.com/javase/specs/jls/se12/html/jls-3.html#jls-3.10.5-410).
The following sections discuss compile-time processing in more detail.
#### 1. Line terminators
Line terminators in the content are _normalized_ from CR (`\u000D`) and CRLF (`\u000D\u000A`)
to LF (`\u000A`) by the Java compiler. This ensures that the string derived from the content
is equivalent across platforms, even if the source code has been translated to a platform
encoding (see `javac -encoding`).
For example, if Java source code that was created on a Unix platform (where the line
terminator is LF) is edited on a Windows platform (where the line terminator is CRLF), then
without normalization, the content would become one character longer for each line. Any
algorithm that relied on LF being the line terminator might fail, and any test that needed to
verify string equality with `String::equals` would fail.
The escape sequences `\n` (LF), `\f` (FF), and `\r` (CR) are _not_ interpreted during
normalization; escape processing happens later.
#### 2. Incidental white space
The text blocks [shown above](#Motivation) were easier to read than their concatenated string
literal counterparts, but the obvious interpretation for the content of a text block would
include the spaces added to indent the embedded string so that it lines up neatly with the
opening delimiter. Here is the HTML example using dots to visualize the spaces that the
developer added for indentation:
``` String html = """ .............. .............. ..............
Hello, world
.............. .............. .............."""; ```
Since the opening delimiter is generally positioned to appear on the same line as the
statement or expression which consumes the text block, there is no real significance to the
fact that 14 visualized spaces start each line. Including those spaces in the content would
mean the text block denotes a string different from the one denoted by the concatenated string
literals. This would hurt migration, and be a recurring source of surprise: it is
overwhelmingly likely that the developer does _not_ want those spaces in the string. Also, the
closing delimiter is generally positioned to align with the content, which further suggests
that the 14 visualized spaces are insignificant.
Spaces may also appear at the end of each line, especially when a text block is populated by
copy-pasting snippets from other files (which may themselves have been formed by copy-pasting
from yet more files). Here is the HTML example reimagined with some trailing white space,
again using dots to visualize spaces:
``` String html = """ ................. .............. ..............
Hello, world
.... .............. . ................. ..............""";
```
Trailing white space is most often unintentional, idiosyncratic, and insignificant. It is
overwhelmingly likely that the developer does not care about it. Trailing white space
characters are similar to line terminators, in that both are invisible artifacts of the source
code editing environment. With no visual guide to the presence of trailing white space
characters, including them in the content would be a recurring source of surprise, as it would
affect the length, hash code, etc, of the string.
Accordingly, an appropriate interpretation for the content of a text block is to differentiate
_incidental white space_ at the start and end of each line, from _essential white space_. The
Java compiler processes the content by removing incidental white space to yield what the
developer intended. `String::indent` can then be used to further manipulate indentation if
desired. Using `|` to visualize margins:
``` || | | | Hello, world
| | | || ```
The _re-indentation algorithm_ takes the content of a text block whose line terminators have
been normalized to LF. It removes the same amount of white space from each line of content
until at least one of the lines has a non-white space character in the leftmost position. The
position of the opening `"""` characters has no effect on the algorithm, but the position of
the closing `"""` characters does have an effect if placed on its own line. The algorithm is
as follows:
1. Split the content of the text block at every LF, producing a list of _individual lines_.
Note that any line in the content which was just an LF will become an empty line in the list
of individual lines.
2. Add all _non-blank_ lines from the list of individual lines into a set of _determining
lines_. (Blank lines -- lines that are empty or are composed wholly of white space -- have no
visible influence on the indentation. Excluding blank lines from the set of determining lines
avoids throwing off step 4 of the algorithm.)
3. If the last line in the list of individual lines (i.e., the line with the closing
delimiter) is _blank_, then add it to the set of determining lines. (The indentation of the
closing delimiter should influence the indentation of the content as a whole -- a
[_significant trailing line_](#Significant-trailing-line-policy) policy.)
4. Compute the _common white space prefix_ of the set of determining lines, by counting the
number of leading white space characters on each line and taking the minimum count.
5. Remove the common white space prefix from each _non-blank_ line in the list of individual
lines.
6. Remove all trailing white space from all lines in the modified list of individual lines
from step 5. This step collapses wholly-white-space lines in the modified list so that they
are empty, but does not discard them.
7. Construct the result string by joining all the lines in the modified list of individual
lines from step 6, using LF as the separator between lines. If the final line in the list from
step 6 is empty, then the joining LF from the previous line will be the last character in the
result string.
The escape sequences `\b` (backspace), `\t` (tab) and `\s` (space) are _not_ interpreted by
the algorithm; escape processing happens later. Similarly, the `\` escape
sequence does not prevent the splitting of lines on the line-terminator since the sequence is
treated as two separate characters until escape processing.
The re-indentation algorithm will be normative in _The Java Language Specification_.
Developers will have access to it via `String::stripIndent`, a new instance method.
#### Significant trailing line policy
Normally, one would format a text block in two ways: first, position the left edge of the
content to appear under the first `"` of the opening delimiter, and second, place the closing
delimiter on its own line to appear exactly under the opening delimiter. The resulting string
will have no white space at the start of any line, and will not include the trailing blank
line of the closing delimiter.
However, because the trailing blank line is considered a _determining line_, moving it to the
left has the effect of reducing the common white space prefix, and therefore reducing the the
amount of white space that is stripped from the start of every line. In the extreme case,
where the closing delimiter is moved all the way to the left, that reduces the common white
space prefix to zero, effectively opting out of white space stripping.
For example, with the closing delimiter moved all the way to the left, there is no incidental
white space to visualize with dots:
``` String html = """
Hello, world
"""; ```
Including the trailing blank line with the closing delimiter, the common white space prefix is
zero, so zero white space is removed from the start of each line. The algorithm thus produces:
(using `|` to visualize the left margin)
``` | | | Hello, world
| | ```
Alternatively, suppose the closing delimiter is not moved all the way to the left, but rather
under the `t` of `html` so it is eight spaces deeper than the variable declaration:
``` String html = """
Hello, world
"""; ```
The spaces visualized with dots are considered to be incidental:
``` String html = """ ........ ........ ........
Hello, world
........ ........ ........"""; ```
Including the trailing blank line with the closing delimiter, the common white space prefix is
eight, so eight white spaces are removed from the start of each line. The algorithm thus
preserves the essential indentation of the content relative to the closing delimiter:
``` | | | Hello, world
| |
```
Finally, suppose the closing delimiter is moved slightly to the _right_ of the content:
``` String html = """
Hello, world
"""; ```
The spaces visualized with dots are considered to be incidental:
``` String html = """ .............. .............. ..............
Hello, world
.............. .............. .............. """; ```
The common white space prefix is 14, so 14 white spaces are removed from the start of each
line. The trailing blank line is stripped to leave an empty line, which being the last line is
then discarded. In other words, moving the closing delimiter to the right of the content has
no effect, and the algorithm again preserves the essential indentation of the content:
``` | | | Hello, world
| | ```
#### 3. Escape sequences
After the content is re-indented, any _escape sequences_ in the content are interpreted. Text
blocks support all of the escape sequences supported in string literals, including `\n`, `\t`,
`\'`, `\"`, and `\\`. See [section
3.10.6](https://docs.oracle.com/javase/specs/jls/se12/html/jls-3.html#jls-3.10.6) of the _The
Java Language Specification_ for the full list. Developers will have access to escape
processing via `String::translateEscapes`, a new instance method.
Interpreting escapes as the final step allows developers to use `\n`, `\f`, and `\r` for
vertical formatting of a string without it affecting the translation of line terminators in
step 1, and to use `\b` and `\t` for horizontal formatting of a string without it affecting
the removal of incidental white space in step 2. For example, consider this text block that
contains the `\r` escape sequence (CR):
``` String html = """ \r \r
Hello, world
\r \r \r """;
```
The CR escapes are not processed until after the line terminators have been normalized to LF.
Using Unicode escapes to visualize LF (`\u000A`) and CR (`\u000D`), the result is:
``` |\u000D\u000A | \u000D\u000A | Hello, world
\u000D\u000A |
\u000D\u000A |\u000D\u000A ```
Note that it is legal to use `"` and `""` freely inside a text block, except immediately
before the closing delimiter. For example, the following text blocks are legal:
``` String story = """ "When I use a word," Humpty Dumpty said, in rather a scornful
tone, "it means just what I choose it to mean - neither more nor less." "The question
is," said Alice, "whether you can make words mean so many different things." "The
question is," said Humpty Dumpty, "which is to be master - that's all." """; //
Note the newline before the closing delimiter
String code = """ String empty = ""; """; ```
However, a sequence of three `"` characters requires at least one `"` to be escaped, in order
to avoid mimicking the closing delimiter. (A sequence of n `"` characters requires at least
`Math.floorDiv(n,3)` of them to be escaped.) The use of `"` immediately before the closing
delimiter also requires escaping. For example:
``` String code = """ String text = \""" A text block inside a text block

String tutorial1 = """ A common character in Java programs is \"""";
String tutorial2 = """ The empty string literal is formed from " characters as
follows: \"\"""";
System.out.println(""" 1 " 2 "" 3 ""\" 4 ""\"" 5 ""\""" 6
""\"""\" 7 ""\"""\"" 8 ""\"""\""" 9 ""\"""\"""\" 10 ""\"""\"""\"" 11
""\"""\"""\""" 12 ""\"""\"""\"""\" """); ```
### New escape sequences
To allow finer control of the processing of newlines and white space, we introduce two new
escape sequences.
First, the `\` escape sequence explicitly suppresses the insertion of a
newline character.
For example, it is common practice to split very long string literals into concatenations of
smaller substrings, and then hard wrap the resulting string expression onto multiple lines:
String literal = "Lorem ipsum dolor sit amet, consectetur adipiscing " +
"elit, sed do eiusmod tempor incididunt ut labore " + "et dolore magna
aliqua.";
With the `\` escape sequence this could be expressed as:
String text = """ Lorem ipsum dolor sit amet, consectetur adipiscing \
elit, sed do eiusmod tempor incididunt ut labore \ et dolore magna
aliqua.\ """;
For the simple reason that character literals and traditional string literals don't allow
embedded newlines, the `\` escape sequence is only applicable to text blocks.
Second, the new `\s` escape sequence simply translates to a single space (`\u0020`).
Escape sequences aren't translated until after incidental space stripping, so `\s` can act as
fence to prevent the stripping of trailing white space. Using `\s` at the end of each line in
this example guarantees that each line is exactly six characters long:
String colors = """ red \s green\s blue \s """;
The `\s` escape sequence can be used in text blocks, traditional string literals, and
character literals.
### Concatenation of text blocks
Text blocks can be used anywhere a string literal can be used. For example, text blocks and
string literals may be concatenated interchangeably:
``` String code = "public void print(Object o) {" + """
System.out.println(Objects.toString(o)); } """; ```
However, concatenation involving a text block can become rather clunky. Take this text block
as a starting point:
``` String code = """ public void print(Object o) {
System.out.println(Objects.toString(o)); } """; ```
Suppose it needs to be changed so that the type of `o` comes from a variable. Using
concatenation, the text block that contains the trailing code will need to start on a new
line. Unfortunately, the straightforward insertion of a newline in the program, as below, will
cause a long span of white space between the type and the text beginning `o` :
``` String code = """ public void print(""" + type + """
o) { System.out.println(Objects.toString(o)); }
"""; ```
The white space can be removed manually, but this hurts readability of the quoted code:
``` String code = """ public void print(""" + type + """ o) {
System.out.println(Objects.toString(o)); } """; ```
A cleaner alternative is to use `String::replace` or `String::format`, as follows:
``` String code = """ public void print($type o) {
System.out.println(Objects.toString(o)); } """.replace("$type",
type); ```
``` String code = String.format(""" public void print(%s o) {
System.out.println(Objects.toString(o)); } """, type); ```
Another alternative involves the introduction of a new instance method, `String::formatted`,
which could be used as follows:
``` String source = """ public void print(%s object) {
System.out.println(Objects.toString(object)); }
""".formatted(type); ```
### Additional Methods
The following methods will be added to support text blocks;
- `String::stripIndent()`: used to strip away incidental white space from the text block
content - `String::translateEscapes()`: used to translate escape sequences -
`String::formatted(Object... args)`: simplify value substitution in the text block
Alternatives ------------
### Do nothing
Java has prospered for over 20 years with string literals that required newlines to be
escaped. IDEs ease the maintenance burden by supporting automatic formatting and concatenation
of strings that span several lines of source code. The `String` class has also evolved to
include methods that simplify the processing and formatting of long strings, such as a method
that presents a string as a [stream of
lines](https://docs.oracle.com/en/java/javase/12/docs/api/java.base/java/lang/String.html#lines()).
However, strings are such a fundamental part of the Java language that the shortcomings of
string literals are apparent to [vast numbers of
developers](https://stackoverflow.com/questions/878573/java-multiline-string). Other JVM
languages have also made advances in how long and complex strings are denoted. Unsurprisingly,
then, multi-line string literals have consistently been one of the most requested features for
Java. Introducing a multi-line construct of low to moderate complexity would have a high
payoff.
### Allow a string literal to span multiple lines
Multi-line string literals could be introduced in Java simply by allowing line terminators in
existing string literals. However, this would do nothing about the pain of escaping `"`
characters. `\"` is the most frequently occurring escape sequence after `\n`, because of
frequency of code snippets. The only way to avoid escaping `"` in a string literal would be to
provide an alternate delimiter scheme for string literals. Delimiters were much discussed for
[JEP 326](https://openjdk.java.net/jeps/326) (Raw String Literals), and the lessons learned
were used to inform the design of text blocks, so it would be misguided to upset the stability
of string literals.
### Adopt another language's multi-string literal
According to [Brian
Goetz](https://mail.openjdk.java.net/pipermail/amber-spec-experts/2019-March/001082.html):
> Many people have suggested that Java should adopt multi-line string literals from Swift or
Rust. However, the approach of “just do what language X does” is intrinsically irresponsible;
nearly every feature of every language is conditioned by other features of that language.
Instead, the game is to learn from how other languages do things, assess the tradeoffs they’ve
chosen (explicitly and implicitly), and ask what can be applied to the constraints of the
language we have and user expectations within the community we have.
For [JEP 326](https://openjdk.java.net/jeps/326) (Raw String Literals), we surveyed many
modern programming languages and their support for multi-line string literals. The results of
these surveys influenced the current proposal, such as the choice of three `"` characters for
delimiters (although there were other reasons for this choice too) and the recognition of the
need for automatic indentation management.
### Do not remove incidental white space
If Java introduced multi-line string literals without support for automatically removing
incidental white space, then many developers would write a method to remove it themselves, or
lobby for the `String` class to include a removal method. However, that implies a potentially
expensive computation every time the string is instantiated at run time, which would reduce
the benefit of string interning. Having the Java language mandate the removal of incidental
white space, both in leading and trailing positions, seems the most appropriate solution.
Developers can opt out of leading white space removal by careful placement of the closing
delimiter.
### Raw string literals
For [JEP 326](https://openjdk.java.net/jeps/326) (Raw String Literals), we took a different
approach to the problem of denoting strings without escaping newlines and quotes, focusing on
the raw-ness of strings. We now believe that this focus was wrong, because while raw string
literals could easily span multiple lines of source code, the cost of supporting unescaped
delimiters in their content was extreme. This limited the effectiveness of the feature in the
multi-line use case, which is a critical one because of the frequency of embedding multi-line
(but not truly raw) code snippets in Java programs. A good outcome of the pivot from raw-ness
to multi-line-ness was a renewed focus on having a consistent escape language between string
literals, text blocks, and related features that may be added in future.
Testing -------
Tests that use string literals for the creation, interning, and manipulation of instances of
`String` should be duplicated to use text blocks too. Negative tests should be added for
corner cases involving line terminators and EOF.
Tests should be added to ensure that text blocks can embed Java-in-Java, Markdown-in-Java,
SQL-in-Java, and at least one JVM-language-in-Java.
JDK-8222777: JEP 359: Records (Preview)
In JDK 14, the [Records (JEP 359)](https://openjdk.java.net/jeps/359) preview feature adds a
new class `java.lang.Record`. The `java.lang` package is implicitly imported on demand, that
is, `import java.lang.*`. If code in an existing source file imports some other package on
demand, for example, `import com.myapp.*;`, and that other package declares a type called
`Record`, then code in the existing source file which refers to that type will not compile
without change. To make the code compile, import the other package's `Record` type using a
single-type import, for example, `import com.myapp.Record;`.
core-libs/java.nio.charsets:
JDK-8229960: Removal of sun.nio.cs.map System Property
The system property `sun.nio.cs.map`, added in JDK 1.4.1, has been removed. It was provided
for applications to help migrate from the old definition of `Shift_JIS`, which was equivalent
to MS Windows codepage 932, to the one that is defined by IANA. Applications that are using
the mapping property will need to designate the correct charset name based on their needs.
hotspot/runtime:
JDK-8225035: Added -XX:+AdjustStackSizeForTLS Flag
The `glibc` library allocates some thread-local storage (TLS) in the stack of a newly created
thread, leaving less stack than requested for the thread to do its work. This is particularly
a problem for threads with small stack sizes. It is an inherited issue from a well-known
`glibc` problem, 'Program with large TLS segments fail' [0] and has been observed in Java
applications. In one of the reported JVM failure instances, the issue manifests as a
`StackOverflowError` on the process reaper thread, which has a small stack size. The
`java.lang.Thread` constructor enables users to specify the stack size for a new thread. The
created thread may encounter the TLS problem when the specified size is too small to
accommodate the on-stack TLS blocks.
In JDK 8, a system property, `jdk.lang.processReaperUseDefaultStackSize`, was introduced to
address the TLS issue only for reaper threads. Setting the property gives a bigger stack size
to the reaper threads.
To address the issue for all threads, a general purpose workaround was implemented in Java
which adjusts thread stack size for TLS. It can be enabled by using the
`AdjustStackSizeForTLS` command-line option:
` -XX:+AdjustStackSizeForTLS`
When creating a new thread, if `AdjustStackSizeForTLS` is true, the static TLS area size is
added to the user requested stack size. `AdjustStackSizeForTLS` is disabled by default.

JDK-8229516: Thread Interrupt State Is Always Available
The specification for `java.lang.Thread::interrupt` allows for an implementation to only track
the interrupt state for live threads, and previously this is what occurred. As of this
release, the interrupt state of a `Thread` is always available, and if you interrupt a thread
`t` before it is started, or after it has terminated, the query `t.isInterrupted()` will
return true.
JDK-8220715: Detailed Message in NullPointerExceptions
A new option is available to provide more helpful `NullPointerException` messages:
-XX:+ShowCodeDetailsInExceptionMessages
If the option is set, on encountering a null pointer, the JVM analyzes the program to
determine which reference was `null` and then provides the details as part of
`NullPointerException.getMessage()`. In addition to the exception message, the method,
filename, and line number are also returned.
By default, this option is disabled.
JDK-8218628: Detailed Message in NullPointerExceptions
A new option is available to provide more helpful `NullPointerException` messages:
-XX:+ShowCodeDetailsInExceptionMessages
If the option is set, on encountering a null pointer, the JVM analyzes the program to
determine which reference was `null` and then provides the details as part of
`NullPointerException.getMessage()`. In addition to the exception message, the method,
filename, and line number are also returned.
By default, this option is disabled.
JDK-8227370: CDS Behavior Change With Non-existent Files During Archive Creation
In JDK 14, CDS runtime classpath validation is now more forgiving when dealing with files in
the classpath that do not exist.
At CDS archive dump time, all non-existent elements in the classpath are automatically
stripped. For example, if the command is:
java -cp nosuchfile.jar:hello.jar -Xshare:dump \
-XX:SharedClassListFile=hello.classlist \ -XX:SharedArchiveFile=hello.jsa
after removing the non-existing elements, the classpath recorded in `hello.jsa` becomes
`hello.jar`.
Also, at run time, when the CDS archive is loaded, all non-existent elements in the classpath
are ignored. With the previous example, all of the following commands will successfully load
the archive:
(1) ``` java -cp nosuchfile.jar:hello.jar -Xshare:on \
-XX:SharedArchiveFile=hello.jsa \ Hello ``` (2) ``` java -cp hello.jar
-Xshare:on \ -XX:SharedArchiveFile=hello.jsa \ Hello ``` (3) ``` java
-cp alsonosuchfile.jar:hello.jar -Xshare:on \ -XX:SharedArchiveFile=hello.jsa \
Hello ```
In JDK 13 and earlier, only (1) is allowed while (2) and (3) would trigger an error.
security-libs/java.security:
JDK-8214024: Removal of the Default keytool -keyalg Value
The default key algorithm for the `keytool -genkeypair` and `keytool -genseckey` commands has
been removed. You must now specify the key algorithm by including the `-keyalg` option when
using the `-genkeypair` or `-genseckey` commands. If the `-keyalg` option is not specified,
the `keytool` will terminate with the error message: "The -keyalg option must be specified".
JDK-8233228: Weak Named Curves in TLS, CertPath, and Signed JAR Disabled by Default
Weak named curves are disabled by default by adding them to the following `disabledAlgorithms`
security properties: `jdk.tls.disabledAlgorithms`, `jdk.certpath.disabledAlgorithms`, and
`jdk.jar.disabledAlgorithms`. The named curves are listed below.
With 47 weak named curves to be disabled, adding individual named curves to each
`disabledAlgorithms` property would be overwhelming. To relieve this, a new security property,
`jdk.disabled.namedCurves`, is implemented that can list the named curves common to all of the
`disabledAlgorithms` properties. To use the new property in the `disabledAlgorithms`
properties, precede the full property name with the keyword `include`. Users can still add
individual named curves to `disabledAlgorithms` properties separate from this new property.
No other properties can be included in the `disabledAlgorithms` properties.
To restore the named curves, remove the `include jdk.disabled.namedCurves` either from
specific or from all `disabledAlgorithms` security properties. To restore one or more curves,
remove the specific named curve(s) from the `jdk.disabled.namedCurves` property.
Curves that are disabled through `jdk.disabled.namedCurves` include the following: secp112r1,
secp112r2, secp128r1, secp128r2, secp160k1, secp160r1, secp160r2, secp192k1, secp192r1,

`java.util.jar.Pack200.Unpacker` have also been removed. These tools and API were deprecated
for removal in Java SE 11 with the express intent to remove them in a future release. In
addition, in the `jar` tool, the `n` sub-option to `jar c` has been removed. See [JEP 367:
Remove the Pack200 Tools and API](https://openjdk.java.net/jeps/367) for more information.
core-libs/java.lang.invoke:
JDK-8173978: MethodHandles::privateLookupIn Requires PRIVATE Lookup Mode
`MethodHandles::privateLookupIn` has been changed. In this release, the caller `Lookup` must
have both `PRIVATE` and `MODULE` access because an application intending to share intra-module
access using `MODULE` alone will inadvertently also share deep reflection to its own module.
In addition, if a `Lookup` object is created by `Lookup::in` or
`MethodHandles::privateLookupIn` teleporting from one module to another module, the `MODULE`
mode is dropped. In other words, `MethodHandles::privateLookupIn` requires that the caller
lookup object must be created by a member from the caller's module and not be produced by
cross-module teleporting.
For example, a lookup object `L` created by calling `MethodHandles.privateLookupIn(C.class,
caller)` (where C is a class in module M1, and the caller's lookup class is in module M0) can
access public members of public class D in module M2 if: - M0 and M1 read M2, and - D is in
a package exported from M2 to at least both M0 and M1.
If D in M2 is accessible to M0 but not to M1, lookup object `L` will fail to lookup members in
D in this release, but would have succeeded in previous releases.
JDK-8173978: Update Lookup::hasPrivateAccess and Lookup::defineClass spec w.r.t. full power lookup
Lookup::hasPrivateAccess intends to return true for "full-power lookup", i.e. a Lookup
produced by the MethodHandles::lookup factory method where the caller class is the lookup
class.
With JDK-8173978, MODULE bit indicates if this lookup object is created by a member in the
same module as the lookup class. MethodHandles::privateLookupIn can produce a Lookup with
MODULE bit dropped if teleporting from another module.
Lookup::hasPrivateAccess should be updated to return true if this lookup has both PRIVATE and
MODULE access.
JDK-8173975: Lookup::in Throws IllegalArgumentException If requestedLookupClass Is a Primitive Type or an Array Class
`java.lang.invoke.MethodHandles.Lookup::in` method throws `IllegalArgumentException` if the
given `requestedLookupClass` is a primitive type, void, or an array class. A `Lookup` object
never intends to allow a lookup class of primitive type, void, or array class. Consequently,
the specification of `Lookup::in` has been fixed in Java SE 14.
JDK-8229785: MethodType::fromMethodDescriptorString Requires "getClassLoader" Permission
`MethodType::fromMethodDescriptorString` has been changed in this release. When a security
manager is present and the `loader` parameter is null, it performs a
RuntimePermission("getClassLoader") security permission check. This check ensures that access
to the system class loader is permitted.
Existing code that calls `MethodType.fromMethodDescriptorString(desc, null)` might get a
`SecurityException` if access to the system class loader is denied. The security policy must
be configured to grant the permission. Applications running without a security manager or
with a non-null loader are not affected by this change.

This new system property sets the pool size of the internal `DocumentBuilder` cache used when

When accessing a STORED entry within a Zip file using `ZipFileInputStream`, a negative value

beyond the beginning of the file, the position is set to the beginning of the file and a
negative value is returned indicating the number of bytes moved from the current position to
the beginning of the file.
When accessing a DEFLATED entry within a Zip file using `ZipFileInflaterInputStream` and a
negative value is specified to the skip method, an `IllegalArgumentException` will be thrown.

JDK-8228396: Stateless Resumption Enabled by Default for JSSE Server
Server-side JSSE now operates in stateless mode by default. As described in RFC 5077[1] for
TLS 1.2 and below, and RFC 8446[2] for TLS 1.3, the TLS server sends internal session
information in the form of an encrypted session ticket to a client that supports stateless.
That session ticket is presented to the server during the TLS handshake to resume the session.
This should improve the performance and memory usage of the TLS server under large workloads
as the session cache will seldom be used. Applications that depend on SSLSession to list
sessions cached will not find that information in stateless mode.
If stateless needs to be turned off, use the System property
`jdk.tls.server.enableSessionTicketExtension`. Using
`-Djdk.tls.server.enableSessionTicketExtension=false` on the command-line will turn off
stateless and return the JSSE server to using the session cache.

JDK-8190492: Removed SSLv2Hello and SSLv3 From Default Enabled TLS Protocols
SSLv2Hello and SSLv3 have been removed from the default enabled TLS protocols.
After this update, if SSLv3 is removed from the `jdk.tls.disabledAlgorithms` security
property, the `SSLSocket.getEnabledProtocols()`, `SSLServerSocket.getEnabledProtocols()`,
`SSLEngine.getEnabledProtocols()` and `SSLParameters.getProtocols()` APIs will return
"TLSv1.3, TLSv1.2, TLSv1.1, TLSv1". "SSLv3" will not be returned in this list.
If a client or server still needs to use the SSLv3 protocol they can do so by enabling it
through the `jdk.tls.client.protocols` or `jdk.tls.server.protocols` system properties or with
the `SSLSocket.setEnabledProtocols()`, `SSLServerSocket.setEnabledProtocols()` and
`SSLEngine.setEnabledProtocols()` APIs.

JDK-8233016: Protected javax.crypto.Cipher Constructor Throws IAE for Non-null Invalid Arguments
The protected constructor of `javax.crypto.Cipher` has been changed to throw

dissolving the association. The issue arises when a `DatagramChannel` is initially bound to an
ephemeral port, connected (by calling its `connect` method), and then disconnected (by calling
its `disconnect` method). The workaround in the `DatagramChannel::disconnect` is to attempt to
re-bind the channel's socket to its original port. This usually succeeds, but if it fails, an
`IOException` is thrown. This workaround has been used in the `DatagramSocket` implementation
for several releases.
As part of this change, the `javadoc` for `DatagramChannel::disconnect` has been updated with
an API note to make it clear that an `IOException` might leave the channel's socket in an
unspecified state. The API note also strongly recommends that the channel be closed when the
`disconnect` fails.
JDK-8223771: Zip File System Throws java.nio.file.NoSuchFileException When the File Does Not Exist and Is Not Being Created
The Zip File System has been updated to throw `java.nio.file.NoSuchFileException` (a
subclass of `IOException`), when `java.nio.file.FileSystems.newFileSystem` is used to create a
new file system; the specified Zip or JAR file does not exist, and the Zip provider property
`create` is not set to `true`.
JDK-8229887: Using the ZIP File System (zipfs) Provider to Update a ZIP or JAR File Containing Uncompressed Entries Might Corrupt the File
Using the ZIP File System (`zipfs`) to update a JAR or ZIP file might corrupt that file.
Corruption occurs only if the JAR or ZIP file contains a non-compressed entry. If the JAR or
ZIP file contains only compressed entries, as is typical, then no data corruption occurs.
As a workaround, users can use the `jar` tool or the `java.util.zip` API to update JAR or ZIP
files that contain non-compressed entries.
JDK-8164993: Clarify the Specification of ReadableByteChannel.read() and Related Methods
The specifications of the `DatagramChannel.receive()`, `FileChannel.read(ByteBuffer,long)`,
`ReadableByteChannel.read()`, and `ScatteringByteChannel.read()` methods have been updated in
this release to specify that an `IllegalArgumentException` is thrown if (any of) the buffer
parameter(s) is read-only. This change merely adjusts the specification to match existing long
term behavior.

JDK-8184193: JEP 349: JFR Event Streaming
JDK Flight Recorder (JFR) now supports continuous monitoring of a Java application by allowing
events to be consumed dynamically using a new API located in the jdk.jfr.consumer package. The
feature is always enabled when using JFR, meaning recorded data up to the last second is
available for both in process and out of process consumption. See [JEP 349: JFR Event
Streaming](https://openjdk.java.net/jeps/349) for more information.

JDK-8232051: Epsilon warns about Xms/Xmx/AlwaysPreTouch configuration
Many Epsilon GC users expect low latency, but may not be aware that additional configuration
is needed for GCs to perform well in those conditions. It now warns about
Xms/Xmx/AlwaysPreTouch configuration. These settings are not adjusted automatically, because
doing so would affect startup time. These new warnings can be shunned by overriding the
default logging level with -Xlog:gc=error.
JDK-8222766: Shenandoah CAS barriers improvements
Following the Load-Reference-Barriers work in JDK 13 (JDK-8221766), Shenandoah improves CAS
barriers to be more efficient. This may translate to higher performance in heavily concurrent
code that deals with lots of object reference CASes, e.g. with AtomicReference.compareAndSet,
VarHandle.compareAndSet, Unsafe.compareAndSet, etc.
JDK-8229358: JEP 364: ZGC on macOS
The Z Garbage Collector (ZGC) is now available as an experimental feature on macOS. To enable
it, use the JVM flags `-XX:+UnlockExperimentalVMOptions -XX:+UseZGC`. See [JEP 364: ZGC on
macOS](https://openjdk.java.net/jeps/364) for more information.
JDK-8231087: Shenandoah self-fixing barriers
Before this improvement, Shenandoah LRB barrier performance penalty for accessing forwarded
objects involved resolving through the forwarding pointer, until the Update References phase
fixed the affected references. A more efficient implementation ships now, where LRB self-fixes
the forwarded reference on the same code path, eliminating continuous resolves for potentially
hot accesses.
Self-fixing is implemented for C1 and C2 (JDK-8231087), interpreter (JDK-8232992) and runtime
(JDK-8232010) barriers.
JDK-8224666: Parallel GC Improvements
Parallel GC has adopted the same task management mechanism for scheduling parallel tasks as
other collectors. This might result in significant performance improvements. Because of this
change, the following product flags have been obsoleted: `-XX:BindGCTaskThreadsToCPUs`,
`-XX:UseGCTaskAffinity`, and `-XX:GCTaskTimeStampEntries`.
JDK-8230646: Epsilon does not extend TLABs to max size
Due to a simple implementation bug, Epsilon GC did not extend the size of the issued TLABs to
the max size configured by user, or set by default. This bug might have introduced performance
penalties and was generally confusing during performance analysis. This is now fixed and
backported to 13u and 11u. Users are advised to double-check their performance results before
and after this update.
JDK-8232575: Shenandoah: asynchronous object/region pinning
When dealing with JNI Get*Critical methods, Shenandoah employs object/region pinning, instead
of using the GCLocker. Until now, the inefficient pinning implementation have caused
real-world scalability problems on workloads that use a lot of JNI, for example gzip and
graphics. This was improved, and scalability bottleneck should be resolved. This fix was also
backported to 8-shenandoah and 11-shenandoah.
JDK-8226241: Shenandoah supports concurrent class unloading
As of JDK 14, Shenandoah GC supports concurrent class unloading. It improves the prior
stop-the-world implementation to be fully concurrent, which minimizes the class unloading work
done during Final Mark pause. This also enables class unloading for the regular GC cycles by
default, in addition to already enabled class unloading during degenerated and full GC cycles.
This relies heavily on runtime facilities introduced in JDK 12, and therefore not available in
11-shenandoah and 8-shenandoah.
JDK-8231086: Shenandoah arraycopy improvements
When handling Object[] arraycopy, Shenandoah used to evacuate array elements / fix references
in the destination array after the copy. This is not efficient when multiple copies are done,
as fixups would have to run on every copy. Plus, the fixups in the destination array do not
improve the accesses to the source array.
Unfortunately, this was the only way to deal with arraycopy until the GC API was extended. In
JDK 14 with GC API improvements, Shenandoah is now able to fix up object arrays at source
before the arraycopy, which improves performance and opens up other optimization
opportunities.
JDK-8210473: JEP 345: NUMA-Aware Memory Allocation for G1
The G1 garbage collector now tries to allocate and keep objects on the same NUMA node in the
young generation across garbage collections. This is similar to Parallel GC NUMA awareness.
G1 attempts to evenly distribute Humongous and Old regions across all available NUMA nodes
using a strict interleave. Placement of objects copied from young to old generation is random.
These new NUMA-Aware Memory Allocation heuristics are automatically enabled by using the
`-XX:+UseNUMA` command line option. See [JEP 345: NUMA-Aware Memory Allocation for
G1](https://openjdk.java.net/jeps/345) for more information.
JDK-8229049: JEP 363: Remove the Concurrent Mark and Sweep (CMS) Garbage Collector
The CMS garbage collector has been removed. `-XX:UseConcMarkSweepGC` and aliases `-Xconcgc`
and `-Xnoconcgc` are obsoleted as well as all CMS specific options (too many to list). See
[JEP 363: Remove the Concurrent Mark Sweep (CMS) Garbage
Collector](https://openjdk.java.net/jeps/363) for more information.
JDK-8232364: JEP 365: ZGC on Windows
The Z Garbage Collector (ZGC) is now available as an experimental feature on Windows. To
enable it, use the JVM flags `-XX:+UnlockExperimentalVMOptions -XX:+UseZGC`. See [JEP 365: ZGC
on Windows](https://openjdk.java.net/jeps/365) for more information.
JDK-8235685: Shenandoah supports JFR Leak Profiler
After the recent improvements in runtime, users should now be able to use JFR Leak Profiler
with Shenandoah GC. This is only available with JDK 14 onwards.
JDK-8233301: JEP 366: Deprecate the ParallelScavenge + SerialOld GC Combination
The ParallelScavenge + SerialOld garbage collector combination has been deprecated. Any use of
the `UseParallelOldGC` command line option, which is used to enable this garbage collection
algorithm combination, will cause a deprecation warning.
The drop-in replacement is to use the ParallelScavenge + ParallelOld garbage collector through
`-XX:+UseParallelGC` on the command line.
See [JEP 366: Deprecate the ParallelScavenge + SerialOld GC
Combination](https://openjdk.java.net/jeps/366) for more information.
