    This appears to be caused by a small timing window which can
    create the ArrayIndexOutOfBoundsException.
    This occurs in very rare situation.
    

Local fix

  • restart server
    

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server versions 7.0, 8.0, and 8.5.          *
    ****************************************************************
    * PROBLEM DESCRIPTION: Application server fails to start       *
    *                      due to ArrayIndexOutOfBoundsException   *
    *                      originating in RMM.                     *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When starting an application server, ArrayIndexOutOfBounds may
    occur due to a small timing window in RMM code. This will
    cause the JVM to panic and terminate.
    

Problem conclusion

  • Code was changed to eliminate the timing window which causes
    this exception.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 7.0.0.33, 8.0.0.9 and 8.5.5.2.  Please refer to the
