RELEASE NOTES:

hotspot/svc:

    JDK-8365057: Thread Dumps Generated by HotSpotDiagnosticMXBean.dumpThreads and jcmd Thread.dump_to_file Updated to Include Owner of the Park Blocker

      The thread dump generated by the [com.sun.management.HotSpotDiagnosticMXBean.dumpThreads] API,
      and the diagnostic command `jcmd <pid> Thread.dump_to_file`, now includes information about
      park blocker owner for threads that are parked on
      [java.util.concurrent.locks.AbstractOwnableSynchronizer] objects.

    JDK-8347938: Add Support for the Latest ML-KEM and ML-DSA Private Key Encodings

      The JDK now encodes ML-KEM and ML-DSA private keys in PKCS #8 format using the DER-encoded
      ASN.1 CHOICE formats defined in [Section 6, "Private Key
      Format"](https://www.rfc-editor.org/rfc/rfc9935.html#name-private-key-format) of RFC 9935 and
      [Section 6, "Private Key
      Format"](https://www.rfc-editor.org/rfc/rfc9881.html#name-private-key-format) of RFC 9881. Two
      new security properties, `jdk.mlkem.pkcs8.encoding` and `jdk.mldsa.pkcs8.encoding`, control
      the encoding used when generating new keys with a `KeyPairGenerator` or when translating keys
      with a `KeyFactory`. Valid values are `seed`, `expandedKey`, and `both` (case-insensitive). If
      a system property of the same name is also specified, it supersedes the security property
      value. All three formats are supported when decoding previously encoded private keys with a
      `KeyFactory`.
      
      When these algorithms were introduced in JDK 24, the encoding format was equivalent to the
      `expandedKey` value. This release changes the default value to `seed`. As a result, ML-KEM and
      ML-DSA private keys generated by this JDK release will not be accepted by older releases by
      default, although keys generated by older releases are still readable by this release. To
      enable older JDK releases to accept ML-KEM and ML-DSA private keys generated by this JDK
      release, set the `jdk.mlkem.pkcs8.encoding` or `jdk.mldsa.pkcs8.encoding` property (whichever
      property is relevant to your use case) to `expandedKey`, and use `KeyFactory.translateKey` to
      convert the key to the older format.

    JDK-8347938: Add Support for the Latest ML-KEM and ML-DSA Private Key Encodings

      The JDK now encodes ML-KEM and ML-DSA private keys in PKCS #8 format using the DER-encoded
      ASN.1 CHOICE formats defined in [Section 6, "Private Key
      Format"](https://www.rfc-editor.org/rfc/rfc9935.html#name-private-key-format) of RFC 9935 and
      [Section 6, "Private Key
      Format"](https://www.rfc-editor.org/rfc/rfc9881.html#name-private-key-format) of RFC 9881. Two
      new security properties, `jdk.mlkem.pkcs8.encoding` and `jdk.mldsa.pkcs8.encoding`, control
      the encoding used when generating new keys with a `KeyPairGenerator` or when translating keys
      with a `KeyFactory`. Valid values are `seed`, `expandedKey`, and `both` (case-insensitive). If
      a system property of the same name is also specified, it supersedes the security property
      value. All three formats are supported when decoding previously encoded private keys with a
      `KeyFactory`.
      
      The default encoding for newly generated ML-KEM and ML-DSA private keys is `seed`.
      Applications that require a particular private-key encoding can configure the relevant
      security property or equivalent system property.

hotspot/jfr:

    JDK-8382740: JFR Event jdk.OldObjectSample Disabled for Generational ZGC

      The JFR event `jdk.OldObjectSample` is disabled when using generational ZGC.
      
      The combination results in unacceptable performance overhead because the implementation relies
      on weak handles that, in generational ZGC, are processed only in the old generation. 

security-libs/java.security:

    JDK-8372351: Added WISeKey Global GB and GC Root CA Certificates

      The following root certificates have been added to the `cacerts` truststore: ``` + WISeKey   +
      wisekeyglobalrootgbca     DN: CN=OISTE WISeKey Global Root GB CA, OU=OISTE Foundation
      Endorsed, O=WISeKey, C=CH
      
      + WISeKey   + wisekeyglobalrootgcca     DN: CN=OISTE WISeKey Global Root GC CA, OU=OISTE
      Foundation Endorsed, O=WISeKey, C=CH ```

core-svc/java.lang.management:

    JDK-8369736: New Management Interface for AOT Cache Creation

      A new management interface, [jdk.management.HotSpotAOTCacheMXBean], has been added to the
      `jdk.management` module to provide the operation `endRecording()`. This operation ends the AOT
      recording and creates the AOT cache and/or configuration file. As with any `MXBean`, the
      operation can be invoked either from within the application or from an external tool such as
      [jconsole].
