[7u6] request for review: 7124400: [macosx] CGraphicsDevice.getConfigurations() returns reference to member (does not copy configs)

[Andrew Brygin]

Hello,

  could you please review a backport of fix for CR 7124400 to 7u6?
  The fix is exactly same as for jdk8: it clones a GraphicsConfiguration
  collection in order to prevent it's modification by an external code.

Bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7124400
Jdk8 changeset: http://hg.openjdk.java.net/jdk8/2d/jdk/rev/7c4eed4b6c19
Webrev: http://cr.openjdk.java.net/~bae/7124400/7u6/webrev.00/

Thanks,
Andrew
