<AWT Dev> [9] Review request for 8178905: Undercorated frame is not painted on OEL7(Gnome3).

[Sergey Bylokhov]

Hi, Semyon.
A few questions:
 - Is it possible to add a test case for this bug? Since the bug was not found by sqe I assume we have no such tests.
 - Is the bug reproducible on jdk8?
 - Is it possible that parentFrame.isTargetUndecorated() may call the users code via XFramePeer->isTargetUndecorated()->Frame.isUndecorated()?
 - I suggest to create a standalone native application and send a bug report to the gnome3 team. Because next year it will be default on Ubuntu as well.
