Dennis Kieselhorst commented on CXF-7475:
-----------------------------------------

Tried your testcase several times but never hit the issue. Could you please attach a thread
dump with stacktrace? Is it hanging in wait()?

> Just found out an issue with shutting down the {{Bus}} when configured with {{AsyncHttpConduit}}.
> *Problem*
> In case it happens, applications won't be able to gracefully shutdown, as it causes requests
to hang on the {{AsyncHTTPConduit.AsyncWrappedOutputStream::getHttpResponse}} indefinitely.
> *How to reproduce*
> This is an edge case, but it happens when the Bus is shutdown after the client started
the request but before getting the ConnectException. Below there is a link to a Junit test
reproducing the problem.
> https://gist.github.com/dwp-joaomelo/80926c3ded0d17e1e94a72245ece2f79
> The test should hang forever on the last statement {{thread.join();}}, that is, waiting
for the request thread to do it's job. 
> Note that you might need to run it a couple of times as it is a timing thing, in case
you cannot reproduce the issue, you might need to tweak the {{Thread.sleep(1000)}}.
