[OpenJDK 2D-Dev] [7u10] request for review: 6997116: The case automatically failed due to java.lang.ClassCastException.

[Andrew Brygin]

Hello,

  could you please review a backport of the fix for 6997116?

  This fix prevents a class cast exception during rendering via d3d
  pipeline under certain circumstances. This fix was done in early
  builds of jdk8 and was not backported to jdk7 updates because the
  problem has quite little visibility.

  However, it looks like the problem is visible on windows8 platform
  (see http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7194578),
  so this fix needs to be backported to 7u10.

  The change is exactly same as for jdk8.

  Please take a look.
