  ****************************************************************
  After adding members to the coregroup, if the configuration
  fails to propogate to all members, the newly added members will
  not be reflected in the defined members list for all members.
  Those members with configuration inconsistencies can throw a
  NullPointerException and JVM panic when the newly added members
  are incorporated into the DCS view.
  

Problem conclusion

• Defined set conflict checks have been expanded and will be
  performed for all core group members when requested to add new
  members to the DCS view.
  
  The fix for this APAR is currently targeted for inclusion in
  fix packs 8.5.5.6 and 8.0.0.11.  Please refer to the
