     DELAY: 6
     JAVACORE
    
    The
    JAVA_DUMP_OPTS was setup to :
    name="JAVA_DUMP_OPTS"

    onSummary(ActionSummaryHandler.java:118)
    .

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server                                      *
    ****************************************************************
    * PROBLEM DESCRIPTION: NullPointerException occurs when        *
    *                      using the Diagnostic Plan's JAVACORE    *
    *                      action along with the IBM_JAVACOREDIR   *
    *                      property set.                           *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    If the IBM_JAVACOREDIR property is set and the Diagnostic Plan
    triggers a JAVACORE action, a NullPointerException occurs, and
    the Diagnostic Plan terminates abruptly.
    

Problem conclusion

  • The code was fixed to resolve the NullPointerException from
    occuring, when the Diagnostic Plan's JAVACORE action is used
    with the IBM_JAVACOREDIR system property set.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.5.5.17 and 9.0.5.2.  Please refer to the Recommended
