Hello, AWT Team.

Sorry for this mess with updates, please review the updated fix for the issue:
http://bugs.sun.com/view_bug.do?bug_id=8005405
The new version is available at:
http://cr.openjdk.java.net/~pchelko/8005405/webrev.02/

As Sergey noticed there was a bug in the previous version: the getParent method 
could return an owner of the window an coordinates would be computed 
incorrectly. In the updated version this issue is solved and the code is 
further simplified.

Thank you.
With best regards. Petr.
