[9] Review request for 8039001 [macosx] Textfields in dialogs are disabled after using F3 on Mac OS X to select a window

[Alexander Scherbatiy]

Hello,
Could you review the fix:
  bug: https://bugs.openjdk.java.net/browse/JDK-8039001
  webrev: http://cr.openjdk.java.net/~alexsch/8039001/webrev.00

  NSRunningApplication active property is false when windowDidBecomeKey 
notification is received after switching
  from the Mission Control on Mac OS X to the modal dialog.

  The fix adds the isAppActive propery to the ApplicationDelegate and 
change it after
  the applicationWillBecomeActive/applicationWillResignActive 
notifications to track the application active state.

  It is difficult to write an automated test because it is hard to find 
the application coordinates in the Mission Control.


Thanks,
Alexandr.
