             Summary: allow MessageListeners to be used when prefetch is configured to 0 
                 Key: QPIDJMS-219
                 URL: https://issues.apache.org/jira/browse/QPIDJMS-219
             Project: Qpid JMS
          Issue Type: Improvement
          Components: qpid-jms-client
    Affects Versions: 0.11.1
            Reporter: Robbie Gemmell
            Assignee: Robbie Gemmell
             Fix For: 0.20.0


Currently if prefetch is configured to 0 via the URI, the client will refuse to let you register a MessageListener with a consumer, requiring it to be set to at least 1. This means you can't do no-prefetch synchronous receives and asynchonous listeners on the same connection (without resorting to use of code to configure custom prefetch policies for each consumer).

Allow listeners when prefetch is set to 0, issuing a single credit when it is registered, and then after each message is consumed.
