RELEASE NOTES

Issue Description
JDK-8184036

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

Issue Description
JDK-8178380

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.
