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: http://cr.openjdk.java.net/~serb/8211435/webrev.00/ On 26/10/2018 15:25, Martin Balao wrote:
