[7u12] Request for approval for CR 8003978: closed/javax/swing/JRootPane/bug4670486.java fails since jdk7u12b01 on macosx

[Alexander Scherbatiy]

Hello,

This is a request to backport a JDK 8 fix into JDK 7u12:

8003978 closed/javax/swing/JRootPane/bug4670486.java fails since 
jdk7u12b01 on macosx
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8003978

The fix has already been pushed to JDK 8, as:
http://hg.openjdk.java.net/jdk8/awt/jdk/rev/9c6ca265b4a1

The code changes for JDK 7u12 are identical to the ones in JDK 8.

Thank you,
  Alexandr.
