Error description

  • After installing the WebSphere MQ (WMQ) File Transfer Edition
    (FTE) v7.0.4.1 plug-in for WMQ Explorer v7.1, the process is
    still listed in the Windows Task manager after a shut down
    of the Explorer GUI. The process name is javaw.exe. This only
    happens when there are many agents defined and with heavy
    workload.
    

Local fix

Problem summary

  • Due to unsynchronized access to a DateFormat Object, a
    NumberFormatException was thrown. The NumberFormatException was
    not caught in the method and the exception was handled at a
    higher level, which resulted in some WebSphere MQ Explorer
    threads ending prematurely.  As a consequence, MQ Explorer could
    not shut down.
    
    USERS AFFECTED:
    All users of the IBM WebSphere MQ File Transfer Edition plugin
    for the IBM WebSphere MQ Explorer
    
    PLATFORMS AFFECTED:
    All
    

Problem conclusion

  • The code was altered to ensure that the DateFormat object is not
    used concurrently over multiple threads.  This prevents the
    NumberFormatException being thrown and allows MQ Explorer to
    clean up the resources that it is using and shutdown
    successfully.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 7.0.4.2.
