Problem summary

  • ****************************************************************
    * USERS AFFECTED:  Users of WebSphere eXtreme Scale who have   *
    *                  eXtremeMemory (XM) enabled on the catalog   *
    *                  server.                                     *
    ****************************************************************
    * PROBLEM DESCRIPTION: The NullPointerException exception      *
    *                      occurs on the catalog server when       *
    *                      eXtremeMemory is enabled.               *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    A problem existed where there was a mismatch on whether
    eXtremeMemory was enabled for a map. The mismatch was
    corrected so that the code correctly determines whether
    eXtremeMemory was enabled for a map.
