RULE "java/awt/Frame/MaximizedToMaximized/MaximizedToMaximized.java" Exception java.lang.RuntimeException: Maximized frame is smaller than non maximized

This failure is intermittent, and for a good reason: there should be sync after setVisible(true) of the frame, and a small delay() wouldn't hurt, either.
Without them, I have a consistent failure on my dual-monitor system which apparently has some performance penalty; with robot.waitForIdle() and a delay, test does pass consistently.
