Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server V9.0                                 *
  ****************************************************************
  * PROBLEM DESCRIPTION: The CDI spec allows dependent scoped    *
  *                      producers to return null, this was      *
  *                      not supported                           *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  In most circumstances it is not valid to inject a null. The
  CDI spec had a special case in which it was possible, but the
  general purpose null checks were not allowing this case
  

Problem conclusion

• New code was written to allow dependent scoped producers to
  bypass he usual null checks
  
  The fix for this APAR is currently targeted for inclusion in
  fix packs 9.0.0.8 an  18.0.0.2.  Please refer to the
