Hello,

Please review a fix for http://bugs.sun.com/view_bug.do?bug_id=7124554 at:

http://cr.openjdk.java.net/~anthony/x-6-alwaysOnTop.0/

Lubomir Nerad (CC'ed) should be credited for the fix itself. I'm just going to integrate it into the repository.

A JWindow object is always a child window with either an explicit parent, or a shared invisible owner frame. Therefore, we always call NSWindow -addChildWindow: when showing a JWindow object. The root cause of the issue is that the -addChildWindow: resets the level of the child window to match that of the parent window. With this fix we restore the level back to its original value after the -addChildWindow: call, and as such preserve the always-on-top state of the child window.

I've verified the fix with a test app attached to the original issue at http://java.net/jira/browse/MACOSX_PORT-158 , and it works fine.

-- best regards, Anthony
