      Run the test to reproduce RESTEASY-3033, it can be found at https://github.com/resteasy/resteasy/pull/2938 .

      If you take in the fix for the deadlock, it will almost always fail with a trace like this:

       Wrong message order in run 6 [msg-1, msg-0, msg-2, msg-3, msg-4, msg-5, msg-6, msg-7, msg-8, msg-9, msg-10, msg-11, msg-12, msg-13, msg-14, msg-15, msg-16, msg-17, msg-18, msg-19, msg-20, msg-21, msg-22, msg-23, msg-24, msg-25, msg-26, msg-27, msg-28, msg-29, msg-30, msg-31, msg-32, msg-33, msg-34, msg-35, msg-36, msg-37, msg-38, msg-39, msg-40, msg-41, msg-42, last-msg-43]

      This problem happens in around 20% of the requests, the tests executes 100 requests.

      When SSE events are quickly send from the server it is possible that the first event send on the server comes in second on the client side.  So the event order is somehow messed up.

      We saw this only happen with the first event.  For all other events the order is correct.

      With the test to reproduce RESTEASY-3033 we found 2 other issues, this is one of them, the other is RESTEASY-3045.
