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:

That's only the first half of this issue, which is indeed easy to fix by just
dispatching SentEvent events. The second half is here:
