Error description

  • When a WebSphere MQ (WMQ) v7 Java Message Service (JMS)
    message-driven bean (MDB) application running in WebSphere
    Application Server v7.0.x tries to get a message and query its
    JMSXGroupID property, a NullPointerException is thrown.
    
    This error is not seen when an identical attempt is made from a
    WMQ v6 MDB application.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users of the WMQ v7 classes for JMS which
    read properties from a message that has been subjected to
    serialization.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows) +Java
    ****************************************************************
    PROBLEM SUMMARY:
    When a WMQ v7 JMS application queries properties including
    JMSXGroupID from a message that has been serialized and
    de-serialized, a NullPointerException is thrown. The difference
    in the WMQ v6 and the WMQv7 serialization procedures led to the
    loss of the values of all such properties and hence led to the
    NullPointerException.
    

Problem conclusion

  • The WMQ v7 code has been fixed so that the values of all the
    message properties are retained after the de-serialization
    process.
