Error description

  • Message CWWKB0152E: Native routine (IWMEJOIN) received a
    failing reason code (2,135) from WLM is seen in messages.log
    when running applications using the servlet-3.1 feature
    along with the zosWlm-1.0 feature.  The servlet must
    implement and use a ReadListener.  Work may be attributed to
    the wrong WLM enclave when this error occurs.

    ****************************************************************
    The web container did not transfer contexts from the main
    servlet thread, to the thread that processes a ReadListener.  In
    some cases the thread that processes a ReadListener was not
    associated with any enclave.  In other cases it was associated
    with the wrong enclave.  In some instances an SMF 120 record
    would not be produced at the end of a request because zosWlm-1.0
    thought that there was still an outstanding ReadListener, when
    in fact they had all completed.  Error CWWKB0152E for service
    IWMEJOIN occurs when the ReadListener thread could not join an
    enclave because it was already in an enclave, and is the most
    common symptom of this problem.
    

Problem conclusion

  • Code was added to transfer the context correctly from the main
    servlet thread, to the threads that process ReadListener
    implementations.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 17.0.0.4.  Please refer to the Recommended Updates page for
