  • Closed as fixed if next.

Error description

  • When a WebSphere MQ Version 7 Java Message Service (JMS)
    application creates multiple asynchronous message consumers for
    the same JMS destination (either a queue or a topic), calling
    consumer.close() fails to close the specified consumer.
    Messages will continue to be delivered to this consumer,
    although delivery to the other message consumers will cease.
    

Local fix

Problem summary

  • This problem is a result of the new Read Ahead functionality
    that was introduced in WebSphere MQ Version 7.
    
    The current queue manager design allows only a single callback
    to be registered for a given queue, and the WebSphere MQ JMS
    Client tries to get around this by sharing this callback
    between consumers that monitor the same queue. However, when
    the close() method is called for one of these consumers, the
    WebSphere MQ JMS Client will invoke the operation on the wrong
    one.
    

Problem conclusion

Temporary fix

Comments

  • This issue is a limitation of the current design of the
    WebSphere MQ Version 7 JMS Client, and cannot be resolved.
