[8] Review request for 8008728 [macosx] Swing. JDialog. Modal dialog goes to background

[Alexander Scherbatiy]

Hello,
Could you review the fix:
  bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8008728
  webrev: http://cr.openjdk.java.net/~alexsch/8008728/webrev.00

  Suppose there are 2 frames and one modal dialog which has the first 
frame as a parent.

  When we click on the second window the canBecomeMainWindow method 
returns NO (the second window
  is disabled because of the modal dialog) and it does not receive the 
windowDidBecomeMain event.
  But Mac OS X system places the second window over the modal dialog.

  The fix checks the right order of windows in the canBecomeMainWindow 
method.

Thanks,
Alexandr.
