-------------------------------------

             Summary: Consumer.receive hangs if http acceptor with non-zero batch-delay is configured
                 Key: ARTEMIS-1186
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-1186
             Project: ActiveMQ Artemis
          Issue Type: Bug
            Reporter: Tomas Hofman


Test scenario:
# Call consumer.receive(1000) on empty queue.
# Check whether receive call is unblocked after the 1 second.

Issue: The receive call is not unblocked.

I hit the issue which was initially reported in JBEAP-6443. I found out that the issue is somehow related to http connectors/acceptors and {{batch-delay}} parameter. I am able to reproduce it only if a client connects via http-connector with non-zero batch-delay. When I tried classic {{remote-connector}}, everything worked with both zero and non-zero {{batch-delay}}.

I am able to reproduce the issue with both Artemis 1.1 (EAP 7.0.3) and Artemis 1.4.

From the thread dump, you can see where the client hangs.
