Please review fix for JDK9:
The test scenario attached to the jira contains potential errors because
Componet.getLocation() won't return the location at any moment of time.
Anyway a window location issue exists in Unity. The root cause is that
the real insets sent with the XA_NET_FRAME_EXTENTS event can be
overridden by the "guessed" insets which are zero on Unity. So the
returned location is increased by real insets while the real window
location is correct.
Yet another issue I found in Unity is a window size issue which is also
caused by the frame insets detection. The Unity WM doesn't provide the
frame insets immediately and XA_NET_FRAME_EXTENTS event may come after
the ConfigureNotify event for the frame.
The solution proposes an adaptation of the existing frame insets request
algorithm to the Unity WM so that makes it more stable.
