Error description

• When the group member cache of nested groups is being handled,
  unnecessary lookups occur in LDAP, which causes performance
  issues trying to resolve all users of a participant group by
  using TWParticipantGroup.allUsersﾎﾚ when the participant group
  contains nested groups defined in IBM Business Process Manager
  (BPM).
  

Local fix

Problem summary

  when one of the subgroups has been refreshed, superfluous checks
  occur.
  

Problem conclusion

• A fix is available for IBM BPM that optimizes the refresh
  implementation by preventing unnecessary checks.
