RELEASE NOTES:

tools/jpackage:

    JDK-8345185: jpackage No Longer Includes Service Bindings by Default for Generated Run-Time Images

      Starting with JDK 25, `jpackage` will no longer include service bindings for a run-time image
      that it creates. Prior to JDK 25, `jpackage` would include service bindings for run-time
      images. As a result, the generated run-time images produced by `jpackage` might not include
      the same set of modules as it did in prior versions.
      
      The previous behavior can be achieved with `jpackage` of JDK 25 by adding the
      `--bind-services` `jlink` option to the default `jlink` options `jpackage` uses:
      
      ``` jpackage [...] --jlink-options \    "--strip-native-commands --strip-debug --no-man-pages
      --no-header-files --bind-services" ```

hotspot/compiler:

    JDK-8349637: Incorrect result of Integer.numberOfLeadingZeros

      `Integer.numberOfLeadingZeros` may return an incorrect result on x86_64 with AVX2. The issue
      is caused by an incorrect JIT compiler optimization. As a workaround, the following
      command-line options can be used `-XX:+UnlockDiagnosticVMOptions
      -XX:DisableIntrinsic=_numberOfLeadingZeros_i`.

security-libs/java.security:

    JDK-8303770: Removed Baltimore CyberTrust Root Certificate after expiry date

      The following expired root certificate has been removed from the `cacerts` keystore: ``` +
      alias name "baltimorecybertrustca [jdk]"   Distinguished Name: CN=Baltimore CyberTrust Root,
      OU=CyberTrust, O=Baltimore, C=IE ```
