  ****************************************************************
  You will see an error such as CNTR0019E: EJB threw an unexpected
  (non-declared) exception during invocation of method
  "onMessage". Exception data: java.lang.NullPointerException when
  running an application that uses CDI and message driven beans.
  

Problem conclusion

• Code was added to allow CDI to recognise that MDBs should not
  return a bean from an ejbDescriptor and allow CDI to work
  regardless.
  
  The fix for this APAR is currently targeted for inclusion in fix
  pack 9.0.5.9 and liberty 21.0.0.7 Please refer to the
