PROBLEM SUMMARY:

USERS AFFECTED:
 All users of IBM WebSphere Application
Server Liberty - Contexts and Dependency
Injection (CDI)

PROBLEM DESCRIPTION:
NullPointerException during invocation
of Message Driven Bean

RECOMMENDATION:
None

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
