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 (Standard)
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, BY COMPONENT:
:
JDK-8234871: deprecate SocketFlow (SO_FLOW_SLA) and related APIs for removal
The SocketFlow and SO_FLOW_SLA socket options are Solaris-specific and should be deprecated
for removal. See http://openjdk.java.net/jeps/362 (JDK-8231554).
The related NetworkPermissions should also be deprecated for removal.
client-libs/2d:
JDK-8230367: 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.
core-libs/java.lang:
JDK-8233196: 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-8233042: 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.
core-libs/java.lang.invoke:
JDK-8228624: 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-8233527: 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-8238458: 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-8230819: 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.
core-libs/java.net:
JDK-8234266: 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-8232369: 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-8234915: 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.
JDK-8234643: 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.
core-libs/java.nio:
JDK-8240909: 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-8231881: DatagramChannel.disconnect Might Leave the Channel's Socket in an Unspecified State
The `DatagramChannel` implementation has been updated in this release so that the `disconnect`
method attempts to workaround Linux kernel behavior that reverts the local port to 0 after
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-8230045: 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.
core-libs/java.nio.charsets:
JDK-8230725: 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.
core-libs/java.text:
JDK-8229146: Accounting Currency Format Support
Currency format instances with accounting style, in which the amount is formatted in
parentheses in some locales, can be obtained by calling
`NumberFormat.getCurrencyInstance(Locale)` with the "u-cf-account" Unicode locale extension.
For example in `Locale.US`, it will format to "`($3.27)`" instead of "`-$3.27`". Refer to
[CLDR's accounting currency format
style](https://www.unicode.org/reports/tr35/tr35-33/tr35-numbers.html#Currency_Formats) for
additional information.
core-libs/java.util:i18n:
JDK-8235444: 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-8233128: 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/javax.lang.model:
JDK-8238893: ExecutableElement.getReceiverType Changed to Return NOTYPE Rather Than null
The specification for `ExecutableElement.getReceiverType` requires it to return `NOTYPE` when
a receiver type is not defined. The implementation has been changed to return `NOTYPE` in this
case rather than null.
core-libs/javax.naming:
JDK-8231406: DnsClient TCP Socket Timeout
The semantics of the `com.sun.jndi.dns.timeout.initial` property of the JNDI DNS provider
implementation have been amended. The value of this timeout now uniformly applies to both UDP
and TCP queries. Previously it applied only to UDP queries.
deploy:
JDK-8226774: 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`.
hotspot/compiler:
JDK-8228418: Turned Off AOT by Default and Changed Related Flags to Experimental
The default value of `UseAOT` has been changed from `enabled` to `disabled`, and the following
AOT support related flags have been changed to experimental:
- `UseAOT` - `PrintAOT` - `AOTLibrary`
hotspot/gc:
JDK-8236248: 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-8237016: 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-8234585: 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.
JDK-8234141: 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-8233390: 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-8234346: 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-8235396: 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-8235755: 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-8236245: 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-8237010: 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-8237009: 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-8237013: 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-8237011: 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-8237012: 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.
hotspot/runtime:
JDK-8234223: 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-8234223: 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-8230291: 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.
JDK-8227417: 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.
Reference: [0] [Bug 11787 - Program with large TLS segments
fail](https://sourceware.org/bugzilla/show_bug.cgi?id=11787)
JDK-8234771: 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.
security-libs/java.security:
JDK-8234774: Added 4 Amazon Root CA Certificates
The following root certificates have been added to the cacerts truststore: ``` + Amazon +
amazonrootca1 DN: CN=Amazon Root CA 1, O=Amazon, C=US
+ amazonrootca2 DN: CN=Amazon Root CA 2, O=Amazon, C=US
+ amazonrootca3 DN: CN=Amazon Root CA 3, O=Amazon, C=US
+ amazonrootca4 DN: CN=Amazon Root CA 4, O=Amazon, C=US ```
JDK-8234215: Added LuxTrust Global Root 2 Certificate
The following root certificate has been added to the cacerts truststore: ``` + LuxTrust +
luxtrustglobalroot2ca
DN: CN=LuxTrust Global Root 2, O=LuxTrust S.A., C=LU ```
JDK-8236730: 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,
secp224k1, secp224r1, secp256k1, sect113r1, sect113r2, sect131r1, sect131r2, sect163k1,

JDK-8228664: Removed Deprecated java.security.acl APIs
The deprecated `java.security.acl` APIs have been removed. This includes the following classes
in that package: `Acl`, `AclEntry`, `AclNotFoundException`, `Group`, `LastOwnerException`,
`NotOwnerException`, `Owner`, and `Permission`.
JDK-8234207: 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".

prime239v3
The implementations of these curves are targeted to be removed in a subsequent JDK release. A
small number of them may be replaced with a more modern implementation.
JDK-8235768: Deprecated the OracleUcrypto JCE Provider for Removal
The OracleUcrypto JCE Provider and its containing module `jdk.crypto.ucrypto` have been
deprecated and are subject to removal in a future version of the JDK. See [JEP
362](https://openjdk.java.net/jeps/362) for more information.
JDK-8234609: Protected javax.crypto.Cipher Constructor Throws IAE for Non-null Invalid Arguments
The protected constructor of `javax.crypto.Cipher` has been changed to throw
`IllegalArgumentException` instead of `NullPointerException` if the supplied arguments are
deemed invalid for constructing the `Cipher` object. If the provider argument is null, the
constructor will throw `NullPointerException` as before. Both exceptions are now documented in
the javadoc specification of the protected constructor.
JDK-8229043: SunJCE Provider Throws NoSuchAlgorithmException for AES/GCM/PKCS5Padding
Prior to this release, the SunJCE provider incorrectly returned a `Cipher` instance for the
"AES/GCM/NoPadding" transformation when a caller requested "AES/GCM/PKCS5Padding". The SunJCE
provider now throws `NoSuchAlgorithmException` when "AES/GCM/PKCS5Padding" is requested. If
you are impacted by this issue, the workaround is to use "AES/GCM/NoPadding" instead.
security-libs/javax.net.ssl:
JDK-8235639: 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.
security-libs/javax.security:
JDK-8233043: 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.
security-libs/javax.xml.crypto:
JDK-8239467: Apache Santuario Library Updated to Version 2.1.4
The Apache Santuario library has been upgraded to version 2.1.4. As a result, a new system
property `com.sun.org.apache.xml.internal.security.parser.pool-size` has been introduced.
This new system property sets the pool size of the internal `DocumentBuilder` cache used when
processing XML Signatures. The function is equivalent to the
`org.apache.xml.security.parser.pool-size` system property used in Apache Santuario and has
the same default value of 20.
specification/language:
JDK-8236439: 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;`.
tools/jar:
JDK-8235712: JEP 367: Remove the Pack200 Tools and API
The `pack200` and `unpack200` tools, added in JDK 5.0, have been removed. The class
`java.util.jar.Pack200` and the interfaces `java.util.jar.Pack200.Packer` and
`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.
tools/javac:
JDK-8235684: 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-8238892: 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.
tools/javap:
JDK-8225811: 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.
xml/javax.xml.transform:
JDK-8229389: 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.
xml/jaxp:
JDK-8230936: New Method to SAX ContentHandler for Handling XML Declaration
A new method `declaration` has been added to `SAX ContentHandler` to receive notification of
the XML declaration. By implementing this method, applications can receive the values of
version, encoding, and standalone attributes exactly as declared in the input document.
