Problem summary

• ****************************************************************
  * USERS AFFECTED:  All IBM WebSphere Application Server V8.5   *
  *                  users of EJB and Asynchbeans                *
  ****************************************************************
  * PROBLEM DESCRIPTION: The getCallerPrincipal method cannot    *
  *                      be called from an asynchbean context    *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The getCallerPrincipal method is only intended to be called
  from an Enterprise Java Beans (EJB) method, so the EJB
  container passes data from the current EJB method context to
  the security component to determine the caller principal.
  When getCallerPrincipal is called from an asynchbean context,
  there is no current EJB method context, so the EJB container
  throws a NullPointerException.
  

Problem conclusion

• EJB container is updated to pass null to the security
  component when there is no current EJB method context, which
  causes UNAUTHENTICATED to be returned.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.4.  Please refer to the Recommended Updates
