Problem conclusion

  • The EJB Container has been updated to wait for the ORB to start
    before completing initialization of remote EJBs. The
    NullpointerException will no longer occur for this scenario.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 17.0.0.3.  Please refer to the Recommended Updates page for
