Hi, Shashi.

Did you check this behavior was in jdk7/8 GA, or it is a regression?

There are platform notifications like the 'windowDidBecomeMain' and 'windowDidBecomeKey' are issued for the window that is about to get the focus and key strokes. So typically under normal conditions, the window which is about to get notified of becoming the focusable window would get the KEY and MAIN notifications in that order.
> But with VO, some how the KEY notification was not delivered to java window and it only receives the MAIN notification. In this scenario, though the isKeyWindow() is true for this window, KEY notification was not delivered and only the MAIN notification is delivered. We do transfer the focus under the KEY notification handler which was not getting executed since it received no KEY notification. Per me, isKeyWindow() and MAIN notification is sufficient to transfer the focus and become a main window but I have not disturbed the existing handlers for the notification and fixed only for the case which is causing this issue.
