The following pseudo-code produces error if <wsdl> is encoded in UTF-16
    (please find the actual code and ant build-script in attachement):

        Endpoint endpoint = Endpoint.create(...);
        URL wsdlURL=new URL(<location of wsdl>);
        endpoint.setMetadata( List<Source>
        {
                new StreamSource(wsdlURL.openStream(),wsdlURL.toExternalForm())
        });
        
        endpoint.publish("http://localhost:8880/hello");

    The exception stack trace is:
