  ****************************************************************
  When a Kerberos token is generated using the
  KRBGenerateLoginModule and there is a serious configuration
  issue, such as an incorrect callback handler is configured,
  when trace is enabled, a NullPointerException error may occur:
  [12/19/14 8:35:59:791 PST] 0000015f WSSecurityGen E
  CWWSS5514E: An exception while processing WS-Security message:

Problem conclusion

• The WS-Security Kerberos token generator is updated so that
  the trace statements do not attempt to access data that does
  not exist.
  
  The fix for this APAR is currently targeted for inclusion in
  fix packs 7.0.0.39, 8.0.0.11 and 8.5.5.6.  Please refer to the
