    RemoteTCPConnection[qmid=QM,fap=9,peer=host/127.0.0.1,

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users of the WebSphere MQ (WMQ) File Transfer
    Edition v7, and can also be seen by users of the WMQ v7 classes
    for Java Message Service (JMS) and WMQ v7 classes for Java
    
    Platforms affected:
     All Distributed (iSeries, all Unix and Windows) +Java
    ****************************************************************
    PROBLEM SUMMARY:
    In the case of network outage WMQ's internal representation of
    the connection is notified that the connection has broken.
    
    If the internal connection had become null, this notification
    failed and a NullPointerException was thrown.
    

Problem conclusion

  • The code has been changed to ensure that the internal connection
    is informed of a failure only if the connection is
    not null.
    
    This prevents the NullPointerException from being thrown by
    the receiver thread.
