    *                      Server a NullPointerException in EMF    *
    *                      (Eclipse Modeling Framework) might      *
    *                      occur.                                  *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    This problem might occur on average after 500 successive server
    starts and stops.
    The version of EMF included in WebSphere Application Server is
    not thread safe.  Any code that makes calls to EMF is required
    to do so in a thread safe manner.
    In this case an initialization step was missed in the
    PmeextPackageImpl class.  The result is that in subsequent
    processing, multiple threads attempted to peform the
    initialization which caused the NullPointerException.
    

Problem conclusion

  • PmeextPackageImpl has been updated to initialize EMF
    EAllStructualFeatures. Subsequent threads will no longer
    attempt to do the initialization because they find the
    initialization is already completed.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.0.0.9 and 8.5.5.3.  Please refer to the Recommended
