<AWT Dev> OpenJdk11-28-EA JDialog hanging

[Sergey Bylokhov]

Hi, Martin.
Thank you for this details description of the problem, I have tried to summarize it in this test, which should fail on all platforms:

http://cr.openjdk.java.net/~serb/8204142/webrev.00/raw_files/new/test/jdk/java/awt/event/SequencedEvent/MultipleContextsUnitTest.java

It creates a number of SequencedEvents and post them in a different orders. It also has some additional checks, for example InvocationEvent posted in between of SequencedEvents should be dispatched in the same order as posted/ or posted not early that SequencedEvents. Some new checks might be added.

Here is another version of the fix which tries to resolve the problem covered by the test above:
http://cr.openjdk.java.net/~serb/8204142/webrev.00/

But I have run it for a night in a bash loop, and it failed after 100+ iterations. So there is some room for improvements.

Note that this fix should be applied on top of JDK-8211435:
