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-8260244 JEP 405: Record Patterns & Array Patterns (Preview)
Enhance the Java programming language with record patterns, to deconstruct record values, and array patterns, to deconstruct array values. Record patterns, array patterns, and type patterns (JEP 394) can be nested so as to significantly enhance the expressiveness and utility of pattern matching.
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-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.



Issue Description

Prohibit Null for Header Keys and Values in

In JDK 18, the handling of header names and values in jdk.httpserver/ 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


Remove the legacy PlainSocketImpl and PlainDatagramSocketImpl implementation

As of JDK 18, the legacy implementations of and 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 the system properties and, used to select these implementations, has also been removed. Setting these properties will now have no effect.


Issue Description

Removed 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.



Removed 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



Issue Description

Call X509KeyManager.chooseClientAlias once for all key types

The (D)TLS implementation in JDK now calls X509KeyManager.chooseClientAlias() only once during handshaking for client authentication, even if there are multiple algorithms requested .


Issue Description

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

ParallelGC supports string deduplication

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


ZGC supports string deduplication

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


Obsolete product options -XX:G1RSetRegionEntries and -XX:G1RSetSparseRegionEntries

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

JDK-8017163 implements a completely new remembered set implementation where these options do not apply any more. So both -XX:G1RSetRegionEntries and -XX:G1RSetSparseRegionEntries have no function any more and their use will trigger an obsoletion warning.


SerialGC supports string deduplication

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