Do I understand that this won't be fixed in the 1.3.X branch? If not, I may have to
try to extend
"AbstractFramedChannel" and apply your fix (
https://github.com/undertow-io/undertow/commit/e7b3f0342e60ad445e18ccde65... ).
Not sure
how easy this will be...
I agree it's not a major issue when running in production. The real problem is that
when the issue
occures my tests take forever to complete.
Thanks Stuart!

Looks like it is an exception that can occur when a server is being
shut down. The close listener attempts to queue a task in the IO
thread, but it is rejected because of the shutdown. It then executes
it directly in the current thread, which results in another attempted
dispatch.
I have created: https://issues.jboss.org/browse/UNDERTOW-791
Should be an easy fix, and should not actually cause any issues
because the server is being shut down anyway (at worst you might miss
an OnClose notification).
