JEPs

Issue Description
JDK-8187041 JEP 400: UTF-8 by Default
Specify UTF-8 as the default charset of the standard Java APIs. With this change, APIs that depend upon the default charset will behave consistently across all implementations, operating systems, locales, and configurations.
JDK-8260510 JEP 408: Simple Web Server
Provide a command-line tool to start a minimal web server that serves static files only. No CGI or servlet-like functionality is available. This tool will be useful for prototyping, ad-hoc coding, and testing purposes, particularly in educational contexts.
JDK-8201533 JEP 413: Code Snippets in Java API Documentation
Introduce an @snippet tag for JavaDoc's Standard Doclet, to simplify the inclusion of example source code in API documentation.
JDK-8266010 JEP 416: Reimplement Core Reflection with Method Handles
Reimplement java.lang.reflect.Method, Constructor, and Field on top of java.lang.invoke method handles. Making method handles the underlying mechanism for reflection will reduce the maintenance and development cost of both the java.lang.reflect and java.lang.invoke APIs.
JDK-8269306 JEP 417: Vector API (Third Incubator)
Introduce an API to express vector computations that reliably compile at runtime to optimal vector instructions on supported CPU architectures, thus achieving performance superior to equivalent scalar computations.
JDK-8263693 JEP 418: Internet-Address Resolution SPI
Define a service-provider interface (SPI) for host name and address resolution, so that java.net.InetAddress can make use of resolvers other than the platform's built-in resolver.
JDK-8274073 JEP 419: Foreign Function & Memory API (Second Incubator)
Introduce an API by which Java programs can interoperate with code and data outside of the Java runtime. By efficiently invoking foreign functions (i.e., code outside the JVM), and by safely accessing foreign memory (i.e., memory not managed by the JVM), the API enables Java programs to call native libraries and process native data without the brittleness and danger of JNI.
JDK-8273326 JEP 420: Pattern Matching for switch (Second Preview)
Enhance the Java programming language with pattern matching for switch expressions and statements, along with extensions to the language of patterns. Extending pattern matching to switch allows an expression to be tested against a number of patterns, each with a specific action, so that complex data-oriented queries can be expressed concisely and safely. This is a preview language feature in JDK 18.
JDK-8274609 JEP 421: Deprecate Finalization for Removal
Deprecate finalization for removal in a future release. Finalization remains enabled by default for now, but can be disabled to facilitate early testing. In a future release it will be disabled by default, and in a later release it will be removed. Maintainers of libraries and applications that rely upon finalization should consider migrating to other resource management techniques such as the try-with-resources statement and cleaners.

RELEASE NOTES

tools/javac

Issue Description
JDK-8202056

Expand checks of javac's serial lint warning


The serial lint warning implemented in javac traditionally checked that a Serializable class declared a serialVersionUID field. The structural checking done by the serial lint warning has been expanded to warn for cases where declarations would cause the runtime serialization mechanism to silently ignore a mis-declared entity, rendering it ineffectual. Also, the checks include several compile-time patterns that could lead to runtime failures. The specific checks include: * For Serializable classes and interfaces, fields and methods with names matching the special fields and methods used by the serialization mechanism are declared properly. * Additional analagous checks are done for Externalizable types as some serialization-related methods are ineffectual there. * A serializable class is checked that it has access to a no-arg constructor in the first non-serializable class up its superclass chain. * For enum classes, since the serialization spec states the five serialization-related methods and two fields are all ignored, the presence of any of those in an enum class will generate a warning. * For record classes, warnings are generated for the ineffectual declarations of serialization-related methods that serialization would ignore. * For interfaces, if a public readObject, readObjectNoData, or writeObject method is defined, a warning is issued since a class implementing the interface will be unable to declare private versions of those methods and the methods must be private to be effective. If an interface defines default writeReplace or readResolve methods, a warning will be issued since serialization only looks up the superclass chain for those methods and not for default methods from interfaces. Since a serialPersistentFields field must be private to be effective, the presence of such a (non-private) field an in interface generates a warning. * For serializable classes without serialPersistentFields, the type of each non-transient instance field is examined and a warning issued if the type of the field cannot be serialized. Primitive types, types declared to be serializable, and arrays can be serialized. While by the JLS all arrays are considered serializable, a warning is issued if the innermost component type is not serializable.

The new warnings can be suppressed using @SuppressWarnings("serial").


JDK-8278318

Index Noteworthy Terms for jdk.compiler and jdk.javadoc Modules


Various terms have been added to the index files in the JDK API documentation, so that these terms can be found in both the static A-Z index and in the interactive search index.

The terms are:
Language Model, Annotation Processing, Compiler API, and Compiler Tree API.


JDK-8272234

Passing Originating Elements From Filer to JavaFileManager


The javax.tools.JavaFileManager has been extended with two new methods, getJavaFileForOutputForOriginatingFiles and getFileForOutputForOriginatingFiles, that are used to create new files with specified originating files. The Filer uses these methods when creating new files (with Filer.createSourceFile, Filer.createClassFile, Filer.createResource) in order to pass along the files containing the originating elements.


JDK-8278373

Corrected References to Overloaded Methods in Javadoc Documentation


For a reference to a specific overload of an overloaded method, the javadoc tool might have linked to the wrong overload in the generated documentation. This fix resolves that issue, and the specified overload will now be used for the links in the generated documentation.


JDK-8271623

Enclosing Instance Fields Omitted from Inner Classes That Don't Use Them


Prior to JDK 18, when javac compiles an inner class it always generates a private synthetic field with a name starting with this$ to hold a reference to the enclosing instance, even if the inner class does not reference its enclosing instance and the field is unused.

Starting in JDK 18, unused this$ fields are omitted; the field is only generated for inner classes that reference their enclosing instance.

For example, consider the following program:

` class T { class I { } } `

Prior to JDK 18, the program would be translated as:

` class T { class I { private synthetic T this$0; I(T this$0) { this.this$0 = this$0; } } } `

Starting in JDK 18, the unused this$0 field is omitted:

` class T { class I { I(T this$0) {} } } `

Note that the form of the inner class constructor is not affected by this change.

The change may cause enclosing instances to be garbage collected sooner, if previously they were only reachable from a reference in an inner class. This is typically desirable, since it avoids a source of potential memory leaks when creating inner classes that are intended to outlive their enclosing instance.

Subclasses of java.io.Serializable are not affected by this change.


core-libs/java.util

Issue Description
JDK-8231640

New System Property to Control the Default Date Comment Written Out by java.util.Properties::store Methods


A new system property, java.properties.date, has been introduced to allow applications to control the default date comment written out by the java.util.Properties::store methods. This system property is expected to be set while launching java. Any non-empty value of this system property results in that value being used as a comment instead of the default date comment. In the absence of this system property or when the value is empty, the Properties::store methods continue to write the default date comment. An additional change has also been made in the implementation of the Properties::store methods to write out the key/value property pairs in a deterministic order. The implementation of these methods now uses the natural sort order of the property keys while writing them out. However, the implementation of these methods continues to use the iteration order when any sub-class of java.util.Properties overrides the entrySet() method to return a different Set than that returned by super.entrySet().

The combination of the deterministic ordering of the properties that get written out with the new system property is particularly useful in environments where applications require the contents of the stored properties to be reproducible. In such cases, applications are expected to provide a fixed value of their choice to this system property.


core-libs/java.net

Issue Description
JDK-8133686

HttpURLConnection's getHeaderFields and URLConnection.getRequestProperties Methods Return Field Values in the Order They Were Added


URLConnection has been fixed to return multiple header values for a given field-name in the order in which they were added.

Previously, if a URLConnection contained multiple header values for a given header field-name, when retrieved by using the HttpURLConnection::getHeaderFields and the URLConnection::getRequestProperties methods, they would be returned in the reverse order to which they were added.

This has been fixed to conform to RFC2616, which explicitly states that the order matters and thus, should be maintained.


JDK-8263693

JEP 418: Internet-Address Resolution SPI


Introduce a service-provider interface (SPI) for host name and address resolution, so that java.net.InetAddress can make use of resolvers other than the platform's built-in resolver. This new SPI allows replacing the operating system's native resolver, which is typically configured to use a combination of a local hosts file and the Domain Name System (DNS).

For further details, see JEP 418.


JDK-8260510

JEP 408: Simple Web Server


jwebserver, a command-line tool to start a minimal static web server, has been introduced. The tool and the accompanying API are located in the com.sun.net.httpserver package of the jdk.httpserver module and are designed to be used for prototyping, ad-hoc coding, and testing, particularly in educational contexts.

For further details, see JEP 408.


JDK-8268960

Prohibit Null for Header Keys and Values in com.sun.net.httpserver.Headers


In JDK 18, the handling of header names and values in jdk.httpserver/com.sun.net.httpserver.Headers has been reconciled. This includes the eager and consistent prohibition of null for names and values. The class represents header names and values as a key-value mapping of Map<String, List <String>>. Previously, it was possible to create a headers instance with a null key or value, which would cause undocumented exceptions when passed to the HttpServer. It was also possible to query the instance for a null key and false would be returned. With this change, all methods of the class now throw a NullPointerException if the key or value arguments are null. For more information, see https://bugs.openjdk.java.net/browse/JDK-8269296.


JDK-8260428

Removal of Support for Pre JDK 1.4 DatagramSocketImpl Implementations


Support for pre JDK 1.4 DatagramSocketImpl implementations (DatagramSocketImpl implementations that don't support connected datagram sockets, peeking, or joining multicast groups on specific network interface) has been dropped in this release. Old implementations have not have been buildable since JDK 1.4 but implementations compiled with JDK 1.3 or older continued to be usable up to this release.

Trying to call connect or disconnect on a DatagramSocket or MulticastSocket that uses an old implementation will now throw SocketException or UncheckedIOException. Trying to call joinGroup or leaveGroup will result in an AbstractMethodError.


JDK-8274227

Removal of impl.prefix JDK System Property Usage From InetAddress


The system property impl.prefix has been removed. This undocumented system property dates from early JDK releases where it was possible to add an implementation of the JDK internal and non-public java.net.InetAddressImpl interface to the java.net package, and have it be used by the java.net.InetAddress API.
The InetAddressResolver SPI introduced by JEP 418 provides a standard way to implement a name and address resolver.


JDK-8253119

Removal of Legacy PlainSocketImpl and PlainDatagramSocketImpl Implementations


Legacy implementations of java.net.SocketImpl and java.net.DatagramSocketImpl have been removed from the JDK. The legacy implementation of SocketImpl has not been used by default since JDK 13, while the legacy implementation of DatagramSocketImpl has not been used by default since JDK 15. Support for system properties jdk.net.usePlainSocketImpl and jdk.net.usePlainDatagramSocketImpl used to select these implementations has also been removed. Setting these properties now has no effect.


security-libs/javax.security

Issue Description
JDK-8267108

Alternate Subject.getSubject and doAs APIs Created That Do Not Depend on Security Manager APIs


New methods javax.security.auth.Subject::current and javax.security.auth.Subject::callAs have been created as replacements for existing methods javax.security.auth.Subject::getSubject and javax.security.auth.Subject::doAs. The javax.security.auth.Subject::getSubject and javax.security.auth.Subject::doAs methods are deprecated for removal because they depend on Security Manager APIs deprecated in JEP 411.


Deprecated Subject::doAs for Removal


Two javax.security.auth.Subject::doAs methods have been deprecated for removal. This is a part of the ongoing effort to remove Security Manager related APIs.


core-libs/java.lang

Issue Description
JDK-8274609

Deprecated Finalization for Removal


The finalization mechanism has been deprecated for removal in a future release. The finalize methods in standard Java APIs, such as Object.finalize() and Enum.finalize(), have also been deprecated for removal in a future release, along with methods related to finalization, such as Runtime.runFinalization() and System.runFinalization().

Finalization remains enabled by default, but it can be disabled for testing purposes by using the command-line option --finalization=disabled introduced in this release. Maintainers of libraries and applications that rely upon finalization should migrate to other resource management techniques in their code, such as try-with-resources and cleaners.

See JEP 421 for further information.


JDK-8277502

Deprecated Finalization for Removal


The finalization mechanism has been deprecated for removal in a future release. The finalize methods in standard Java APIs, such as Object.finalize() and Enum.finalize(), have also been deprecated for removal in a future release, along with methods related to finalization, such as Runtime.runFinalization() and System.runFinalization().

Finalization remains enabled by default, but it can be disabled for testing purposes by using the command-line option --finalization=disabled introduced in this release.

See JEP 421 for further information.


JDK-8277861

Terminally Deprecated Thread.stop


Thread.stop is terminally deprecated in this release so that it can be degraded in a future release and eventually removed. The method is inherently unsafe and has been deprecated since Java 1.2 (1998).


client-libs/2d

Issue Description
JDK-8273102

Removal of Empty finalize() Methods in java.desktop Module


The java.desktop module had a few implementations of finalize() that did nothing. These methods were deprecated in Java 9 and terminally deprecated in Java 16. These methods have been removed in this release. See https://bugs.openjdk.java.net/browse/JDK-8273103 for details.


security-libs/javax.crypto:pkcs11

Issue Description
JDK-8264849

SunPKCS11 Provider Supports AES Cipher With KW and KWP Modes if Supported by PKCS11 Library


The SunPKCS11 provider has been enhanced to support the following crypto services and algorithms when the underlying PKCS11 library supports the corresponding PKCS#11 mechanisms:
AES/KW/NoPadding Cipher <=> CKMAESKEYWRAP mechanism
AES/KW/PKCS5Padding Cipher <=> CKM
AESKEYWRAPPAD mechanism
AES/KWP/NoPadding Cipher <=> CKM
AESKEYWRAP_KWP mechanism


JDK-8255409

SunPKCS11 Provider Now Supports Some PKCS#11 v3.0 APIs


PKCS#11 v3.0 adds several new APIs that support new function entry points, as well as message-based encryption for AEAD ciphers, etc. For JDK 18, the SunPKCS11 provider has been updated to support some of the new PKCS#11 v3.0 APIs. To be more specific, if the "functionList" attribute in the provider configuration file is not set, the SunPKCS11 provider will first try to locate the new PKCS#11 v3.0 CGetInterface() method before falling back to the CGetFunctionList() method to load the function pointers of the native PKCS#11 library. If the loaded PKCS#11 library is v3.0, then the SunPKCS11 provider will cancel crypto operations by trying the new PKCS#11 v3.0 C_SessionCancel() method instead of finishing off remaining operations and discarding the results. Support for other new PKCS#11 v3.0 APIs will be added in later releases.

JEP 420: Pattern Matching for switch (Second Preview)


Enhance the Java programming language with pattern matching for switch expressions and statements, along with extensions to the language of patterns. Extending pattern matching to switch allows an expression to be tested against a number of patterns, each with a specific action, so that complex data-oriented queries can be expressed concisely and safely.

For further details, see JEP 420.


core-libs/java.nio.charsets

Issue Description
JDK-8270490

Charset.forName() Taking fallback Default Value


A new method Charset.forName() that takes fallback charset object has been introduced in java.nio.charset package. The new method returns fallback if charsetName is illegal or the charset object is not available for the name. If fallback is passed as null the caller can check if the named charset was available without having to catch the exceptions thrown by the Charset.forName(name) method.


JDK-8187041

JEP 400: UTF-8 by Default


Starting with JDK 18, UTF-8 is the default charset for the Java SE APIs. APIs that depend on the default charset now behave consistently across all JDK implementations and independently of the user’s operating system, locale, and configuration. Specifically, java.nio.charset.Charset#defaultCharset() now returns UTF-8 charset by default. The file.encoding system property is now a part of the implementation specification, which may accept UTF-8 or COMPAT. The latter is a new property value that instructs the runtime to behave as previous releases. This change is significant to users who call APIs that depend on the default charset. They can try whether they'd be affected or not, by specifying -Dfile.encoding=UTF-8 as the command line option with the existing Java runtime environment. Refer to the JEP for more detail: https://openjdk.java.net/jeps/400

Release Doesn't Correctly Recognize Windows Server


This release doesn't correctly identify Windows Server. The property os.name is set to Windows 2019 on Windows Server 2022. In HotSpot error logs, the OS is identified as Windows 10.0 for Windows Server releases 2016, 2019, and 2022; however, the HotSpot error log does show the Build number. Windows Server 2016 has Build 14393 or above, Windows Server 2019 has Build 17763 or above, and Windows Server 2022 has Build 20348 or above.

This release doesn't correctly identify Windows 11. The property os.name is set to Windows 10 on Windows 11. In HotSpot error logs, the OS is identified as Windows 10; however, the HotSpot error log does show the Build number. Windows 11 has Build 22000.194 or above.


security-libs/java.security

Issue Description
JDK-8225083

Removal of Google's GlobalSign Root Certificate


The following root certificate from Google has been removed from the cacerts keystore: ``` + alias name "globalsignr2ca [jdk]" Distinguished Name: CN=GlobalSign, O=GlobalSign, OU=GlobalSign Root CA - R2

```


JDK-8275252

Migrate cacerts From JKS to Password-Less PKCS12


The cacerts keystore file is now a password-less PKCS #12 file. All certificates inside are not encrypted and there is no MacData for password integrity. Since the PKCS12 and JKS keystore types are interoperable, existing code that uses a JKS KeyStore to load the cacerts file with any password (including null) continue to behave as expected and can view or extract the certificates contained within the keystore.


JDK-8269039

Disabled SHA-1 Signed JARs


JARs signed with SHA-1 algorithms are now restricted by default and treated as if they were unsigned. This applies to the algorithms used to digest, sign, and optionally timestamp the JAR. It also applies to the signature and digest algorithms of the certificates in the certificate chain of the code signer and the Timestamp Authority, and any CRLs or OCSP responses that are used to verify if those certificates have been revoked.

To reduce the compatibility risk for applications that have been previously timestamped, there is one exception to this policy:

  • Any JAR signed with SHA-1 algorithms and timestamped prior to January 01, 2019 will not be restricted.

This exception might be removed in a future JDK release.

Users can, at their own risk, remove these restrictions by modifying the java.security configuration file (or override it by using the java.security.properties system property) and removing "SHA1 usage SignedJAR & denyAfter 2019-01-01" from the jdk.certpath.disabledAlgorithms security property and "SHA1 denyAfter 2019-01-01" from the jdk.jar.disabledAlgorithms security property.


JDK-8231107

Allow Store Password to Be Null When Saving a PKCS12 KeyStore


Calling keyStore.store(outputStream, null) on a PKCS12 KeyStore creates a password-less PKCS12 file. The certificates inside the file are not encrypted and the file contains no MacData. This file can then be loaded with any password (including null) when calling keyStore.load(inputStream, password).


JDK-8272163

New Option -version Added to keytool and jarsigner Commands


A new -version option has been added to the keytool and jarsigner commands. This option is used to print the program version of keytool and jarsigner.


JDK-8225181

KeyStore Has a getAttributes Method


A KeyStore::getAttributes method has been added that returns the attributes of an entry without having to retrieve the entry first. This is especially useful for a private key entry that has attributes that are not protected but previously could only be retrieved with a password.


JDK-8270380

Change the java.security.manager System Property Default Value to disallow


The default value of the java.security.manager system property has been changed to disallow. Unless the system property is set to allow on the command line, any invocation of System.setSecurityManager(SecurityManager) with a non-null argument will throw an UnsupportedOperationException.


JDK-8225082

Removal of IdenTrust Root Certificate


The following root certificate from IdenTrust has been removed from the cacerts keystore: ``` + alias name "identrustdstx3 [jdk]" Distinguished Name: CN=DST Root CA X3, O=Digital Signature Trust Co.

```


JDK-8251468

X509Certificate.get{Subject,Issuer}AlternativeNames and getExtendedKeyUsage Now Throw CertificateParsingException if Extension Is Unparseable


The JDK implementation (as supplied by the SUN provider) of X509Certificate::getSubjectAlternativeNames, X509Certificate::getIssuerAlternativeNames and X509Certificate::getExtendedKeyUsage now throws CertificateParsingException instead of returning null when the extension is non-critical and unparseable (badly encoded or contains invalid values). This change in behavior is compliant with the specification of these methods.


JDK-8274471

Support for RSASSA-PSS in OCSP Response


An OCSP response signed with the RSASSA-PSS algorithm is now supported.


core-libs/java.lang:reflect

Issue Description
JDK-8271820

JEP 416: Reimplement Core Reflection With Method Handles


JEP 416 reimplements core reflection with method handles. Code that depends upon highly implementation-specific and undocumented aspects of the existing implementation might be impacted. Issues that might arise include: - Code that inspects the internal generated reflection classes (such as, subclasses of MagicAccessorImpl) no longer works and must be updated. - Code that attempts to break the encapsulation and change the value of the private final modifiers field of Method, Field and Constructor class to be different from the underlying member might cause a runtime error. Such code must be updated.

To mitigate this compatibility risk, you can enable the old implementation as a workaround by using -Djdk.reflect.useDirectMethodHandle=false. We will remove the old core reflection implementation in a future release. The -Djdk.reflect.useDirectMethodHandle=false workaround will stop working at that point.


core-libs/java.time

Issue Description
JDK-8274407

Update Timezone Data to 2021c


The IANA Time Zone Database, on which the JDK's Date/Time libraries are based, has made a tweak to some of the time zone rules in 2021c.

Note that in 2021b, which is cumulatively included in this change, some of the time zone rules prior to the year 1970 have been modified according to changes introduced with 2021b. For more details, refer to the announcement of 2021b.


core-libs/javax.annotation.processing

Issue Description
JDK-8273157

printError, printWarning, and printNote methods on Messager


For annotation processors, the Messager interface now has methods printError, printWarning, and printNote to directly report errors, warnings, and notes, respectively.


core-libs/java.io:serialization

Issue Description
JDK-8278087

Deserialization Filter and Filter Factory Property Error Reporting Were Under Specified


Invalid values of the command line and the security properties of jdk.serialFilterand jdk.serialFilterFactory are reported by throwing java.lang.IllegalStateException on the first use. The property values are checked when constructing java.io.ObjectInputStream or when calling the methods of java.io.ObjectInputFilter.Config including getSerialFilter() and getSerialFilterFactory(). The IllegalStateException indicates that the serial filter or serial filter factory is invalid and cannot be used; deserialization is disabled. Previously, the exception thrown was ExceptionInInitializerError.


JDK-8276665

ObjectInputStream.GetField.get(name, object) Throws ClassNotFoundException


The java.io.ObjectInputStream.GetField.get(String name, Object val) method now throws ClassNotFoundException when the class of the object is not found. Previously, null was returned, which prevented the caller from correctly handling the case where the class was not found. The signature of GetField.get(name, val) has been updated to throw ClassNotFoundExceptionand a ClassNotFoundException exception is thrown when the class is not found.

The source compatibility risk is low. The addition of a throws ClassNotFoundException should not cause a source compatibility or a compilation warning. The GetField object and its methods are called within the context of the readObject method and include throws ClassNotFoundException.

To revert to the old behavior, a system property, jdk.serialGetFieldCnfeReturnsNull, has been added to the implementation. Setting the value to true reverts to the old behavior (returning null); leaving it unset or to any other value results in the throwing of ClassNotFoundException.


security-libs/org.ietf.jgss:krb5

Issue Description
JDK-8274656

Removal of default_checksum and safe_checksum_type From krb5.conf


The "defaultchecksum" and "safechecksumtype" settings in the krb5.conf configuration file are no longer supported. The checksum type in a KRBTGSREQ message is derived from the type of the encryption key used to generate it. The "safechecksum_type" setting was never used in Java.


JDK-8273670

Removed Weak etypes From Default krb5 etype List


Weak encryption types based on DES, 3DES, and RC4 have been removed from the default encryption types list in Kerberos. These weak encryption types can be enabled (at your own risk) by adding them to the "permittedenctypes" property (or alternatively, the "defaulttktenctypes" or "defaulttgtenctypes" properties) and setting "allowweak_crypto" to "true" in the krb5.conf configuration file.


core-libs/javax.lang.model

Issue Description
JDK-8140442

Method to Get Outermost Type Element


In the javax.lang.model API, the Elements utility interface has a new method, getOutermostTypeElement, which returns the outermost class or interface syntactically enclosing an element.


JDK-8275308

Mapping between SourceVersion and Runtime.Version


The SourceVersion enum class has methods to map between SourceVersion values and Runtime.Version values. In turn, Runtime.Version can be used to map from a string representation of a version to a Runtime.Version object.


JDK-8224922

Map from an Element to its JavaFileObject


The method Elements.getFileObjectOf(Element) maps from an Element to the file object used to create the element.


core-libs

Issue Description
JDK-8277863

Deprecated sun.misc.Unsafe Methods That Return Offsets


Developers that use the unsupported sun.misc.Unsafe API should be aware that the methods that return base and field offsets have been deprecated in this release. The methods objectFieldOffset, staticFieldOffset, and staticFieldBase methods are an impediment to future changes. A future release will eventually degrade or remove these methods along with the heap accessor methods.

The java.lang.invoke.VarHandle API (added in Java 9) provides a strongly typed reference to a variable that is safe and a replacement to many cases that use field offsets and the heap accessor methods. It is strongly recommended to migrate to the VarHandle API where possible. Multi-Release JARs can be used by libraries and frameworks that continue to support JDK 8 or older.


JDK-8269306

JEP 417: Vector API (Third Incubator)


Introduce an API to express vector computations that reliably compile at runtime to optimal vector instructions on supported CPU architectures, thus achieving performance superior to equivalent scalar computations.

For further details, see JEP 417.


JDK-8273401

Disabled JAR Index Support


JAR Index has been disabled in this release. JAR Index was an optimization to postpone downloading of JAR files when loading applets or other classes over the network. JAR Index has many long standing issues and does not interact well with newer features (such as, Multi-Release JARs and modular JARs). If a JAR file contains an INDEX.LIST file, then its contents are ignored by the application class loader and by any URLClassLoader created by user code.

The system property, jdk.net.URLClassPath.enableJarIndex, can be used re-enable the feature if required. If set to an empty string or the value "true", then JAR Index will be re-enabled. This system property is temporary. A future release will remove the JAR Index feature and the system property.

The change does not impact the jar -i option. The jar tool continues to create an index when this option is used.


JDK-8274073

JEP 419: Foreign Function & Memory API (Second Incubator)


Introduce an API by which Java programs can interoperate with code and data outside of the Java runtime. By efficiently invoking foreign functions (i.e., code outside the JVM), and by safely accessing foreign memory (i.e., memory not managed by the JVM), the API enables Java programs to call native libraries and process native data without the brittleness and danger of JNI.

For further details, see JEP 419.

JDK-8193682

Default JDK compressor will be closed when IOException is encountered


DeflaterOutputStream.close() and GZIPOutputStream.finish() methods have been modified to close out the associated default JDK compressor before propagating a Throwable up the stack. ZIPOutputStream.closeEntry() method has been modified to close out the associated default JDK compressor before propagating an IOException, not of type ZipException, up the stack.

Improve Compilation Replay


Compilation Replay has been improved to make it more stable and catch up with new JVM features. Enhancements include: - Best-effort support for hidden classes, allowing more cases involving invokedynamic, MethodHandles, and lambdas to replay successfully - DumpReplay support for C1 - Incremental inlining support - Numerous bug fixes to improve stability

Compilation Replay is a JVM feature of debug builds that is mainly used to reproduce crashes in the C1 or C2 JIT compilers.

Fix Issues With the KW and KWP Modes of SunJCE Provider


Support for AES/KW/NoPadding, AES/KW/PKCS5Padding and AES/KWP/NoPadding ciphers is added to SunJCE provider since jdk 17. The cipher block size for these transformations should be 8 instead of 16. In addition, for KWP mode, only the default IV, i.e. 0xA65959A6, is allowed to ensure maximum interoperability with other implementations. Other IV values will be rejected with exception during Cipher.init(...) calls.

Issue Description
JDK-8251329

Zip File System Provider Throws ZipException When Entry Name Element Contains "." or ".."


The ZIP file system provider has been changed to reject existing ZIP files that contain entries with "." or ".." in name elements. ZIP files with these entries cannot be used as a file system. Invoking the java.nio.file.FileSystems.newFileSystem(...) methods throw ZipException if the ZIP file contains these entries.


JDK-8275149

ReadableByteChannel::read No Longer Throws ReadOnlyBufferException


ReadableByteChannel::read no longer incorrectly throws ReadOnlyBufferException.

The read(ByteBuffer) method of the ReadableByteChannel returned by java.nio.channels.Channel.newChannel(InputStream) was incorrectly throwing ReadOnlyBufferException when its ByteBuffer parameter specified a read-only buffer. ReadableByteChannel::read is, however, specified in this case to throw an IllegalArgumentException. The implementation has been changed for this case to throw an IllegalArgumentException instead of a ReadOnlyBufferException, as dictated by the specification.

Issue Description
JDK-8266936

JDK Flight Recorder Event for Finalization


A new JDK Flight Recorder Event, jdk.FinalizerStatistics, identifies classes at runtime that use finalizers. The event is enabled by default in the JDK (in the default.jfc and profile.jfc JFR configuration files). When enabled, JFR will emit a jdk.FinalizerStatistics event for each instantiated class with a non-empty finalize() method. The event includes: the class that overrides finalize(), that class's CodeSource, the number of times the class's finalizer has run, and the number of objects still on the heap (not yet finalized). For information about using JFR, see the User Guide.

If finalization has been disabled with the --finalization=disabled option, no jdk.FinalizerStatistics events are emitted.

Issue Description
JDK-8272374

DocLint Reports Missing Descriptions


DocLint detects and reports documentation comments that do not have a description about the associate declaration before any block tags that may be present. DocLint is a feature of the javac and javadoc tools that detects and reports issues in documentation comments.


JDK-8273034

Improved Navigation on Small Devices


The pages generated by the Standard Doclet provide improved navigation controls when the pages are viewed on small devices.


JDK-8276964

Indicate Invalid Input in Generated Output


When the Standard Doclet encounters content in a documentation comment that it cannot process, it may create an element in the generated output to indicate clearly to the reader that the output at that position is not as the author intended. (This replaces the earlier behavior to show either nothing or the invalid content.) The element will contain a short summary message and may contain additional details. This is in addition to the existing behavior to report diagnostics and to return a suitable exit code.


JDK-8275786

Options to Include Script Files in Generated Documentation


The Standard Doclet supports an --add-script option used to include a reference to an external script file in the file for each page of generated documentation.


JDK-8269401

Merge "Exceptions" and "Errors" into "Exception Classes"


The "Exceptions" and "Errors" tabs in documentation generated by JavaDoc have been merged into a single "Exception Classes" tab, which includes all exception classes, as defined in JLS 11.1.1.


JDK-8189591

@SuppressWarnings for DocLint Messages


You can now use @SuppressWarnings annotations to suppress messages from DocLint about issues in documentation comments, when it is not possible or practical to fix the issues that were found. For more details, see Suppressing Messages in the DocLint section of the javadoc Tool Guide.


JDK-8201533

JEP 413: Code Snippets in Java API Documentation


An @snippet tag for JavaDoc's Standard Doclet has been added, to simplify the inclusion of example source code in API documentation.

For further details, see JEP 413 and A Programmmer's Guide to Snippets.


core-libs/java.io

Issue Description
JDK-8276970

Default charset for PrintWriter That Wraps PrintStream


The java.io.PrintStream, PrintWriter, and OutputStreamWriter constructors that take a java.io.OutputStream and no charset now inherit the charset when the output stream is a PrintStream. This is important for usages such as: ` new PrintWriter(System.out) where it would be problematic ifPrintStreamdidn't use the same charset as that used bySystem.out. This change was needed because [JEP 400](https://openjdk.java.net/jeps/400) makes it is possible, especially on Windows, that the encoding ofSystem.outis not UTF-8. This would cause problems ifPrintStreamwere wrapped with aPrintWriter` that used UTF-8.

As part of this change, java.io.PrintStream now defines a charset() method to return the print stream's charset.


JDK-8275145

file.encoding System Property Has an Incorrect Value on Windows


The initialization of the file.encoding system property on non macOS platforms has been reverted to align with the behavior on or before JDK 11. This has been an issue especially on Windows where the system and user's locales are not the same.


hotspot/gc

Issue Description
JDK-8267186

ZGC Supports String Deduplication


The Z Garbage Collector now supports string deduplication (JEP 192).


JDK-8272773

Configurable Card Table Card Size


JDK-8272773 introduces the VM option -XX:GCCardSizeInBytes used to set a size of the area that a card table entry covers (the "card size") that is different from the previous fixed value of 512 bytes. Permissible values are now 128, 256, and 512 bytes for all platforms, and 1024 bytes for 64 bit platforms only. The default value remains 512 bytes.

The card size impacts the amount of work to be done when searching for references into an area that is to be evacuated (for example, young generation) during garbage collection. Smaller card sizes give more precise information about the location of these references, often leading to less work during garbage collection. At the same time, however, smaller card sizes can lead to more memory usage in storing this information. The increase in memory usage might result in slower performance of maintenance work during the garbage collection.


JDK-8017163

Obsoleted Product Options -XX:G1RSetRegionEntries and -XX:G1RSetSparseRegionEntries


The options -XX:G1RSetRegionEntries and -XX:G1RSetSparseRegionEntries have been obsoleted with the changes from JDK-8017163.

JDK-8017163 implements a completely new remembered set implementation in which these two options no longer apply. In this release, neither -XX:G1RSetRegionEntries nor -XX:G1RSetSparseRegionEntries have a function, and their use will trigger an obsoletion warning.


JDK-8277212

ZGC: Fixed Long Process Non-Strong References Times


A bug has been fixed that could cause long "Concurrent Process Non-Strong References" times with ZGC. The bug blocked the GC from making significant progress, and caused both latency and throughput issues for the Java application.

The long times could be seen in the GC logs when running with -Xlog:gc*: ` [17606.140s][info][gc,phases ] GC(719) Concurrent Process Non-Strong References 25781.928ms `


JDK-8267185

ParallelGC Supports String Deduplication


The Parallel Garbage Collector now supports string deduplication (JEP 192).


JDK-8275056

Allow G1 Heap Regions up to 512MB


The JDK-8275056 enhancement extends the maximum allowed heap region size from 32MB to 512MB for the G1 garbage collector. Default ergonomic heap region size selection is still limited to 32MB regions maximum. Heap region sizes beyond that must be selected manually by using the -XX:G1HeapRegionSize command line option.

This can be used to mitigate both inner and outer fragmentation issues with large objects on large heaps.

On very large heaps, using a larger heap region size may also decrease internal region management overhead and increase performance due to larger local allocation buffers.


JDK-8272609

SerialGC Supports String Deduplication


The Serial Garbage Collector now supports string deduplication (JEP 192).
