    * PROBLEM DESCRIPTION: java.lang.StackOverflowError occurs     *
    *                      when processing JAX-WS client           *
    *                      application's packaged WSDL.            *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The problem is caused by an issue in the open source WSDL4J
    component which is used to parse the packaged WSDL and
    associated schema.  WSDL4J does not process circular
    dependencies within the WSDL and schema correctly resulting in
    an infinite recursion within the WSDL4J code.
    The reason this occurred in version 8 and did not occur in
    version 7 is because additional processing of WS-Policy in the
    client's packaged WSDL was mandated in the later version of the
    JAX-WS specification supported in version 8.  This now
    mandates that WS-Addressing WS-Policy in the WSDL is honoured
    as a conformance requirement, therefore processing of
    the client's packaged WSDL is an additional step in version 8
    that was not performed in version 7.
    

Problem conclusion

  • The processing of the JAX-WS Client's packaged WSDL for
    WSDL and associated schema should not contain circular
    dependencies, though the specification does not prohibit this.
    It is advisable to resolve the issue by refactoring the WSDL
    and associated schema to avoid circular dependencies.
    
    Since the processing of WS-Addressing WS-Policy in the
    JAX-WS client's packaged WSDL may not be desirable (since it
    is a change of behaviour from previous versions), that
    processing can now be disabled by setting the JVM system
    property
    
    com.ibm.ws.wspolicy.v7migration.disableClientWSDLWSPolicyProcess
    ing
    
    to a value of true.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 8.0.0.14, 8.5.5.12 and 9.0.0.4.  Please refer to the
