RELEASE NOTES:

tools/javac:

    JDK-8225377: `TypeMirror` Changed to Provide Annotations for Types Loaded from Bytecode

      The implementation of `TypeMirror` now provides access to annotations for types loaded from
      bytecode. Previously type annotations were not associated with types loaded from bytecode.
      
      Annotation processors can access type annotations for elements using
      `AnnotationMirror#getAnnotationMirrors`, and the annotations will be included in the output of
      `AnnotationMirror#toString`.
      
      Any programs that relied on annotations being omitted for elements loaded from the classpath
      should be updated to handle type annotations.

core-libs/java.net:

    JDK-8308593: `TCP_KEEPxxxx` Extended Socket Options Are Now Supported on the Windows Platform

      The `java.net.ExtendedSocketOptions` `TCP_KEEPIDLE` and `TCP_KEEPINTERVAL` are supported on
      Windows platforms starting from Windows 10 version 1709 and onwards. `TCP_KEEPCOUNT` is
      supported starting from Windows 10 version 1703 and onwards.

hotspot/compiler:

    JDK-8315082: ZGC: Reintroduced Support for Non-Default ObjectAlignmentInBytes

      The JDK 21 issue that could potentially lead to JVM crashes or incorrect execution when
      running the JVM with `-XX:+UseZGC` and non-default value of `-XX:ObjectAlignmentInBytes` has
      been resolved, and it is possible again to use this combination of JVM options.

core-libs/java.nio:

    JDK-8316304: `BasicFileAttributes.creationTime` Returns Birth Time on Linux

      On Linux (kernel version 4.11 or newer, glibc version 2.28 or newer),
      `BasicFileAttributes.creationTime` now returns the creation or birth time of the file through
      the `stx_btime` element of `struct statx`. In previous JDK releases, the last modified time
      was returned. If the birth time is supported by the platform but not by the file system, then
      the epoch `1970-01-01T00:00:00Z` is returned.

hotspot/runtime:

    JDK-8317772: NMT: Make Peak Values Available in Release Builds

      NMT reports will now show peak values for all categories. Peak values contain the highest
      value for committed memory in a given NMT category over the lifetime of the JVM process.
      
      If the committed memory for an NMT category is currently at peak, NMT prints "at peak";
      otherwise, it prints the peak value.
      
      For example: ``` -                  Compiler (reserved=230KB, committed=230KB)                
      (malloc=34KB #64) (peak=49KB #71)                              (arena=196KB #4) (peak=6126KB
      #16) ```
      
      This shows Compiler arena memory peaked at a bit more than 6MB, whereas it now hovers around
      200 KB.

    JDK-8316735: Hotspot `hs_err` Files Now Print the Lock Stack

      A section containing the thread local lock stack has been added to `hs_err` report files. It
      only gets printed when the new lightweight locking mode is enabled (`-XX:LockingMode=2`).
      
      An example is given here with details about the locked objects omitted: ``` Lock stack of
      current Java thread (top to bottom): LockStack[1]: nsk.share.jdi.EventHandler  ...
      LockStack[0]: java.util.Collections$SynchronizedRandomAccessList ... ``` It lists objects
      which are lightweight locked, through `synchronized` methods or statements, by the Java thread
      which is being analyzed. The object which has been locked most recently is printed first.
      Objects which are not lightweight locked are not displayed in this section. 

    JDK-8316735: Print LockStack in hs_err files

      We have seen bugs related to the new locking which is used by default since JDK-8315880. It
      would be helpful to see the LockStack of a crashing JavaThread in hs_err files.

    JDK-8313782: Add User Facing Warning If THPs Are Enabled but Cannot Be Used

      On Linux, if the JVM is started with `+UseTransparentHugePages` but the system does not
      support Transparent Huge Pages, a warning will now be printed to stdout:
      
      `UseTransparentHugePages disabled; transparent huge pages are not supported by the operating
      system.` 

security-libs/java.security:

    JDK-8317374: Added ISRG Root X2 CA Certificate from Let's Encrypt

      v2   + teliarootcav2     DN: CN=Telia Root CA v2, O=Telia Finland Oyj, C=FI ```

    JDK-8319187: Added Three Root Certificates from eMudhra Technologies Limited

      The following root certificates have been added to the cacerts truststore: ``` + eMudhra
