Hi, Dmitry.
Why the problem is reproduced in JWindow? Why it works in JFrame?

Hello,
Could you review the fix for jdk9, please?
bug: https://bugs.openjdk.java.net/browse/JDK-8032872
webrev: http://cr.openjdk.java.net/~dmarkov/8032872/jdk9/webrev.00/
Problem description: It is impossible to make a selection in JComboBox
added to JWindow via the mouse. The problem is caused by incorrect
mouse events handling in LWWindowPeer class. When LWWindowPeer
receives a mouse event intended for a popup window, it checks whether
the current grabbingWindow is owner of the popup using
getOwnerFrameDialog() method. This approach always fails for the
JComboBox added to JWindow. As a result an UngrabEvent is send to the
popup window.
Fix: Introduce new private method
LWWindowPeer.isOneOfOwnersOf(LWWindowPeer peer). The method will be
invoked on grabbingWindow object to test whether it is owner of
current mouse event target or not. The usage of getOwnerFrameDialog()
should be replaced by isOneOfOwnersOf() in
LWWindowPeer.notifyMouseEvent() and LWWindowPeer.NotifyNCMouseDown().
Thanks,
Dmitry
