JDK-8072110 - Toolkit.realSync() forces a lot of graphical tests to fail on embedded devices
Description
The tests generate some user input event by robots (mouse events or key events) and immediately expect results. On slow devices in batch mode such approach leads to failure.
Other possibility: SunToolkit.realSync does not work as expected.
One-by-one tests passes.

JDK-Regression test suite.
Comments
God point about unexpected focus change. Need to find out a way to look at real job execution.

And, e.g. javax/swing/JMenu/4515762/bug4515762.java sets autodelay 250 for the robot. Note that if tests fail running in a sequence but pass one by one it may sometimes mean (1) some asocial tests leave key releases unprocessed; (2) original focused widget (such as Terminal) tends to steal focus from Java. Second trouble is easily detected just looking on the screen if you have several GUI tests failing in a batch AND a pristine environment (not VNC etc. but exact environment of the failure). As to the first failure, see for example JDK-8064575 and several more fixes in jdk9 to that effect.

What windows manager do you have on those systems? How about JDK-7033533 backport for 8u60, is it in place together with JDK-8051857 ?
