Hi Laurent,

 

Sorry, I could not get to the root cause yet. Seems like it might take some time and some hard debugging.

 

Meanwhile, I’m attaching a simple patch file which effectively reverts the earlier fix that was done for JDK-8152974.

Please try this and let me know if this solves your problem. Then I’ll create a backout bug and push this patch.

 

Thanks,

Krishna

Any progress on this bug, krishna ?

 

At least could you explain how SequencedEvent should be processed when multiple AppContexts are present ?

 

I could help but I have no clue what's going on ... I observed multiple several EDT, AppContexts, awt events, it is very complicated to understand such event handling.

 

Cheers,

Laurent

Hi Laurent,

 

Thanks for providing the test case. I was able to reproduce the issue. Glad to know that you found a workaround, as this issue is a bit tricky to fix.

Great.

 

Meanwhile, I’m looking into fixing this issue, and your test case greatly helps me toward finding the fix faster.

 

I tried diagnosing the bug in EDT/SequencedEvent using heap dumps ... but I got no clues, very tricky.

 

Good luck,

Laurent
