I'm try to resume an AsyncResponse with Netty 4 NettyJaxrsServer on a separate thread as seen in [2].

The AsyncResponse succeeds but the resume method fails after returning with an internal exception [3].

It seems related to how ResteasyProviderFactory.getContextDataMap() and ResteasyProviderFactory.clearContextData() interact. After the AsyncResponse commits the context is cleared which cause the "resume" method to fail because it cannot find UriInfo.

I was expecting getContextDataMap to push a context map on the stack, but it gets overwritten instead.

Surprisingly, this only happens JacksonJaxbJsonProvider and ResteasyJackson2Provider have been registered with ResteasyProviderFactory and ResteasyDeployment [1].

[1] ----

ObjectMapper objectMapper = new ObjectMapper();

ResteasyJackson2Provider resteasyJackson2Provider = new ResteasyJackson2Provider();
resteasyJackson2Provider.setMapper(objectMapper);

ResteasyProviderFactory factory = ResteasyProviderFactory.getInstance();

JacksonJaxbJsonProvider provider = new JacksonJaxbJsonProvider();
factory.registerProviderInstance(provider);

Jackson2JsonpInterceptor interceptor = new Jackson2JsonpInterceptor();
factory.registerProviderInstance(interceptor);

NettyJaxrsServer server = new NettyJaxrsServer();
ResteasyDeployment deployment = new ResteasyDeployment();
deployment.setProviderFactory(factory);
deployment.setApplication(new Application() {
@Override
public Set<Object> getSingletons()

{ HashSet<Object> hashSet = new HashSet<>(); hashSet.add(new TestEndpoint()); return hashSet; }

});
server.setDeployment(deployment);
server.start();

[2] -------------

@Path("/test")
public class TestEndpoint {
static LinkedList<AsyncResponse> responses = new LinkedList<AsyncResponse>();

@GET
@Path("resume")
public String resume()

{ responses.pollFirst().resume("resume"); return "resume"; }

@GET
@Path("async")
public void async(@Suspended final AsyncResponse test)

{ test.setTimeout(1, TimeUnit.DAYS); responses.add(test); }

}
