RELEASE NOTES:

tools/javac:

    JDK-8317300: Align `javac` with the Java Language Specification by Rejecting `final` in Record Patterns

      JDK 21 introduced pattern matching in the Java language. However, `javac` allowed `final` in
      front of a record pattern, such as (`case final R(...) ->`), something which is not allowed by
      the Java Language Specification.
      
      Programs that could be compiled erroneously in JDK21 with `final` will now fail to compile.
      This change fixes the issue in the compiler. Impacted users will need to remove the `final`
      keyword.

    JDK-8319124: Update XML Security for Java to 3.0.3

      The XML Signature implementation has been updated to Santuario 3.0.3. Support for four new
      SHA-3 based RSA-MGF1 `SignatureMethod` algorithms have been added:
      `SignatureMethod.SHA3_224_RSA_MGF1`, `SignatureMethod.SHA3_256_RSA_MGF1`,
      `SignatureMethod.SHA3_384_RSA_MGF1`, and `SignatureMethod.SHA3_512_RSA_MGF1`.

    JDK-8319124: Update XML Security for Java to 3.0.3

      The XML Signature implementation has been updated to Santuario 3.0.3. Support for four new
      SHA-3 based RSA-MGF1 signature methods have been added: `SHA3_224_RSA_MGF1`,
      `SHA3_256_RSA_MGF1`, `SHA3_384_RSA_MGF1`, and `SHA3_512_RSA_MGF1`. While these new algorithm
      URIs are not defined in `javax.xml.crypto.dsig.SignatureMethod` in the JDK update releases,
      they may be represented as string literals in order to be functionally equivalent. SHA-3 hash
      algorithm support was delivered to JDK 9 via [JEP 287](https://openjdk.org/jeps/287). Releases
      earlier than that may use third party security providers.

hotspot/runtime:

    JDK-8325496: Make `TrimNativeHeapInterval` a Product Switch

      `TrimNativeHeapInterval` has been made an official product switch. It allows the JVM to trim
      the native heap at periodic intervals.
      
      This option is only available on Linux with glibc.

client-libs/java.awt:

    JDK-8322750: AWT SystemTray API Is Not Supported on Most Linux Desktops

      The `java.awt.SystemTray` API is used for notifications in a desktop taskbar and may include
      an icon representing an application. On Linux, the Gnome desktop's own icon support in the
      taskbar has not worked properly for several years due to a platform bug. This, in turn, has
      affected the JDK's API, which relies upon that.
      
      Therefore, in accordance with the existing Java SE specification,
      `java.awt.SystemTray.isSupported()` will return false where ever the JDK determines the
      platform bug is likely to be present.
      
      The impact of this is likely to be limited since applications always must check for that
      support anyway. Additionally, some distros have not supported the SystemTray for several years
      unless the end-user chooses to install non-bundled desktop extensions.

security-libs/java.security:

    JDK-8321408: Added Certainly R1 and E1 Root Certificates

      The following root certificates have been added to the cacerts truststore: ``` + Certainly   +
      certainlyrootr1     DN: CN=Certainly Root R1, O=Certainly, C=US
      
      + Certainly   + certainlyroote1     DN: CN=Certainly Root E1, O=Certainly, C=US ```

hotspot/gc:

    JDK-8325074: JVM May Crash or Malfunction When Using ZGC and Non-Default `ObjectAlignmentInBytes`

      Running the JVM with `-XX:+UseZGC` and non-default value of `-XX:ObjectAlignmentInBytes` may
      lead to JVM crashes or incorrect execution. 

    JDK-8310031: Parallel: Precise Parallel Scanning of Large Object Arrays for Young Collection Roots

      During a young collection, ParallelGC partitions the old generation into 64kB stripes when
      scanning it for references into the young generation. These stripes are assigned to worker
      threads that do the scanning in parallel as work units.
      
      Before this change, Parallel GC always scanned these stripes completely even if only a small
      part had been known to contain interesting references. Additionally, every worker thread
      processed the objects that start in that stripe by itself, including parts of objects that
      extend into other stripes.  This behavior limited parallelism when processing large objects. A
      single large object, potentially containing thousands of references, had been scanned by a
      single thread only and in full. This would cause bad scaling due to memory sharing and cache
      misses in the subsequent long, work stealing phase.
      
      With this change, Parallel GC workers limit work to their stripe and only process interesting
      parts of large object arrays. This reduces the work done by a single thread for a stripe,
      improves parallelism, and reduces the amount of work stealing. Parallel GC pauses are now on
      par with G1 in presence of large object arrays, reducing pause times by 4-5 times in some
      cases.
