Dmytro Khrystiuk commented on CXF-7116:
---------------------------------------
Yes, you're right that such behaviour is reproducible only in case of using
embedded jetty transport.
Regarding reproducing in tests, it's important that calls to service during
test are inside loop. In case when we're executing only single call to service
without subsequent one all is working fine. So such behaviour appears only in
case of subsequent calls to async method.
> AsyncResponse.resume() infinitely hangs up after first call

> Environment: * Java - 1.8.0_66 (build 1.8.0_66-b17)
> * CXF - 3.1.8
> * Jetty - 9.3.13.v20161014

> Issue with AsyncResponse happened after upgrade from CXF 3.1.7 to 3.1.8.
> After the second call to REST method server stops to respond. Implementation
> of method uses AsyncResponse and call to resume() in a separate thread:
> @GET
> @Produces(MediaType.TEXT_PLAIN)
> @Path("/doesNotWork")
> public void doesNotWork(@Suspended AsyncResponse response) {
> executorService.submit(() -> {
> LOGGER.debug("Async task...");
> response.resume("Success!");
> });
> }
> First call to method above works as it should but subsequent calls just hangs
> up forever. No thread deadlocks were detected.
> The example test (Maven project) is attached to this item.
