RELEASE NOTES, BY COMPONENT:

hotspot/compiler:

  JDK-8184175: AVX-512 (AVX3) instructions set support

      JDK 9 will support code generation for AVX-512 (AVX3) instructions set on x86 CPUs, but not by
      default. A maximum of AVX2 is supported by default in JDK 9. The flag -XX:UseAVX=3 can be used
      to enable AVX-512  code generation on CPUs that support it.

core-libs/java.lang.module:

  JDK-8180425: Attach API cannot be used to attach to the current VM by default

      The implementation of Attach API has changed in JDK 9 to disallow attaching to the current VM
      by default. This change should have no impact on tools that use the Attach API to attach to a
      running VM. It may impact libraries that mis-use this API as a way to get at the
      java.lang.instrument API. The system property `jdk.attach.allowAttachSelf` may be set on the
      command line to mitigate any compatibility with this change.
