    ****************************************************************
    Access to the queue that holds the asynchronous internal
    loggers needs to be synchronized to handle timing conditions
    where the queue might be emptied by the time another
    asynchronous logger gets queued.
    This is most likely to be seen with FFDC loggers as these
    loggers are configured to be asynchronous.  The
    NullPointerException will occur when WsLogger.queueAsyncEvent
    gets invoked.
    

Problem conclusion

  • Access to the queue that holds the asynchronous internal
    loggers has been synchronized to handle timing conditions
    where the queue might be emptied by the time another
    asynchronous logger gets queued.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 7.0.0.31.  Please refer to the Recommended Updates
