[7u4] Request for approval for 7105890 - closed/javax/swing/JScrollBar/4708809/bug4708809.java deadlocks on MacOS

[Alexander Scherbatiy]

Hello,

This is a request to backport a JDK 8 fix into JDK 7u4:

7105890 closed/javax/swing/JScrollBar/4708809/bug4708809.java deadlocks 
on MacOS
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7105890


The fix has already been pushed to JDK 8, as:
http://hg.openjdk.java.net/jdk8/awt/jdk/rev/18925904efc2


The code changes for jdk7u4 are identical to the ones in jdk8.

Thank you,
  Alexandr.
