RELEASE NOTES:

security-libs/javax.net.ssl:

    JDK-8259662: SocketExceptions Are Not Wrapped Into SSLExceptions in SSLSocketImpl

      This release reverts the behavior of SSLSocketImpl and SSLTransport introduced by JDK-8196584.
      SocketException will now be thrown as is instead of being suppressed into an SSLException.

hotspot/runtime:

    JDK-8313083: Print 'rss' and 'cache' As Part of the Container Information

      The HotSpot runtime code has been updated to additionally print a container's 'rss' and
      'cache'. The additional output can be found in the JVM's response to a "jcmd [PID] VM.info"
      request and in the `hs_err` file generated in case of JVM abrupt termination.
      
      This will help monitoring and troubleshooting OutOfMemory situations as OOM killer can
      terminate a process if its `rss` + `cache` usage reaches the max memory limit of the
      container.
