Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All IBM WebSphere Application Server V7.0   *
    *                  users of WSDL4J                             *
    ****************************************************************
    * PROBLEM DESCRIPTION: NullPointerException thrown while       *
    *                      printing a WSDL document.               *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    A NullPointerException was thrown while WSDL4J was printing a
    WSDL document with the following (partial) stack:
    
    java.lang.NullPointerException
    at org.apache.xerces.dom.ParentNode.nodeListGetLength(Unknown
    Source)
    at org.apache.xerces.dom.ParentNode.getLength(Unknown Source)
    at com.ibm.wsdl.util.xml.DOM2Writer.print(DOM2Writer.java:277)
    ...
    
    The root cause was that WSDL4J was using Node.getChildNodes()
    to print the document, which is not thread safe in the parser
    being used.
    

Problem conclusion

  • DOM2Writer has been changed to use the thread safe operations
    Node.getFirstChild() and Node.getNextSibling() rather than
    Node.getChildren().
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 7.0.0.13.  Please refer to the Recommended Updates
