Christopher L. Shannon commented on AMQ-9481:
-
I don't have a windows environment to test but I was able to reproduce this by
using a clientId like the example and just hitting the rest API from my browser
multiple times. It works the first time, but then the second time I get the
error since the original async request never completes correctly even on
timeout when there are no messages.
I took a look at this and it turns out this was _almost_ fixed in AMQ-9330. The
root cause is AsyncServletRequest that was created to replace the Jetty
Continuation object does not handle timeouts correctly. In AMQ-9330 the code
was changed to call complete() but turns out that makes things better but is
stil not all the way correct.
As shown here, we should be calling dispatch() on the context when timing out:
[https://github.com/jetty/jetty.project/blob/jetty-9.4.54.v20240208/jetty-continuation/src/main/java/org/eclipse/jetty/continuation/Servlet3Continuation.java#L239]
I have a fix and test and will open up a Pull request, with the new fix after
the async request times out then things are cleaned up correctly and future
requests will work. If the original async request is still open then the
concurrent access error will be given.

This is due to the move from Jetty Continuation to AsyncRequestServlet. Let me
