What's new in this version:

Removed Features and Options:
Security-libs/javax.security:
- Remove the Alternate ThreadLocal Implementation of the Subject::current and Subject::callAs APIs
- The “jdk.security.auth.subject.useTL” system property and the alternate ThreadLocal implementation of the Subject::current and Subject::callAs APIs have been removed. The default implementation of these APIs is still supported.
- See JDK-8282676 (not public)

Other Notes:
Hotspot/runtime:
CPU Shares Ignored When Computing Active Processor Count:
- Previous JDK releases used an incorrect interpretation of the Linux cgroups parameter "cpu.shares". This might cause the JVM to use fewer CPUs than available, leading to an under utilization of CPU resources when the JVM is used inside a container.
- Starting from this JDK release, by default, the JVM no longer considers "cpu.shares" when deciding the number of threads to be used by the various thread pools. The -XX:+UseContainerCpuShares command-line option can be used to revert to the previous behavior. This option is deprecated and may be removed in a future JDK release.
- See JDK-8281181

Tools/javac:
Lambda Deserialization Fails for Object Method References on Interfaces:
- Deserialization of serialized method references to Object methods, which was using an interface as the type on which the method is invoked, can now be deserialized again. Note the classfiles need to be recompiled to allow the deserialization.
- See JDK-8282080

Bug Fixes:
- This release also contains fixes for security vulnerabilities described in the Oracle Critical Patch Update
