RELEASE NOTES:

hotspot/runtime:

    JDK-8198794: Better Stability with Older NUMA Libraries (-XX:+UseNuma)

      A fix included in JDK 8 Update 152 introduced a regression that might cause the HotSpot JVM to
      crash during startup when the UseNUMA flag is used on Linux systems with versions of libnuma
      older than 2.0.9. This issue has been resolved. 

client-libs/java.awt:

    JDK-8166772: Touch Keyboard for Swing/AWT Text Components

      This release adds support for automatically showing the touch keyboard for Swing/AWT text
      components on Microsoft Windows 8 or later. A user can display the touch keyboard either by
      using a touch screen to tap the text component area or by using a mouse to click in the area,
      when a keyboard is not attached to a computer.
      
      The system property `awt.touchKeyboardAutoShowIsEnabled` controls whether this functionality
      is enabled in the JDK. This functionality is enabled by default. However, if the functionality
      is not needed, the user can switch it off from the command line by setting the system property
      to `false`:
      
      `-Dawt.touchKeyboardAutoShowIsEnabled=false`
