    PROBLEM DESCRIPTION:
    The JMSOutput Node may emit a NullPointerException with the
    following traceback stack if the JMS Provider fails during a
    timing window in between creation of a JMS context object and
    creation of the JMSMessage object to hold message data:
    
    java.lang.NullPointerException at
    com.ibm.broker.jmsclientnodes.JMSClientMessageFormatterMbToJms.c

    ientOutputNode.java:504) at
    com.ibm.broker.plugin.MbNode.evaluate(MbNode.java:1451)
    
    The error will occur at close to the same time as a BIP4648E
    exception with text similar to the following:
    
    BIP4648E: JMSClient.Broker 'brokerName'; Execution Group
    'egName'; Message Flow 'flowName' Node 'flowName' The connection
    with the JMS provider could not start, or has closed for Initial
    Context factory 'connectionFactoryClassName'. The  node will try
    to re-establish the connection. ', true
    

Problem conclusion

  • A NullPointerException no longer occurs, instead a BIP4644
    message is thrown indicating that a Session has been closed.
