[7u40] Request for approval for CR 8014924 JToolTip#setTipText() sometimes (very often) not repaints component.

[Alexander Scherbatiy]

Hello,

This is a request to backport a JDK 8 fix into JDK 7u14:

8014924 JToolTip#setTipText() sometimes (very often) not repaints component.
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8014924

The fix has already been pushed to JDK 8, as:
  http://hg.openjdk.java.net/jdk8/awt/jdk/rev/6261e94e9869

The code changes for JDK 7u40 are identical to the ones in JDK 8.

Thank you,
  Alexandr.
