Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users of WebSphere MQ File Transfer Edition
    v7.0.4 on z/OS who are using a Java SDK at v7 or above.
    
    
    Platforms affected:
    z/OS
    
    ****************************************************************
    PROBLEM SUMMARY:
    When a transfer to an invalid location occurred and the Java SDK
    in use is at v7 or above, then the WebSphere MQ File Transfer
    Agent would ABEND.
    
    This is due to a change in behaviour at version 7 of the JZOS
    API, which means that a null value can now be returned when
    attempting to retrieve a dataset name. This null value was not
    handled correct by the agent, which caused the
    NullPointerException, and subsequently the ABEND.
    

Problem conclusion

  • The agent code has been modified to tolerate a null response
    from the Java SDK v7 or above when trying to obtain the
    dataset name for a transfer location.
