    * PROBLEM DESCRIPTION: WebSphere Application Server for z/OS   *
    *                      ABEND in bbgoereg.deregisterWorkUnit    *
    ****************************************************************

    ****************************************************************
    An ABEND0C4 occurred in module bbgoereg in bbooereg.cpp's
    deregisterWorkUnit routine referencing the regtok parameter.
    The regtok parameter value was NULL. The ABENDS0C4 occurred in
    the JNI routine GetByteArrayRegion.
    

Problem conclusion

  • Code has been added to check for NULL parameters in the native
    part bbooereg.cpp.  If a NULL parameter is detected a
    java/lang/IllegalArgumentException will be returned to the java
    caller.  Also, code was modified in the java invoking code to
    not make the native call without a valid regtok parameter.
    
    The fix for this APAR is targeted for inclusion in fix packs
    8.5.5.19 and 9.0.5.6. For more information, see 'Recommended
    Updates for WebSphere Application Server':
