We're using buggy xalan version causing namespaces issues

JAXB internally uses JAXP API 1.3 (in our case endorsed java xalan)

When I pass the following XML

<?xml version='1.0' encoding='UTF-8'?>
<EndpointReference xmlns='http://www.w3.org/2005/08/addressing'>
<Address>http://localhost:8080/jaxws-endpointReference</Address>
<Metadata wsdli:wsdlLocation='http://org.jboss.ws/endpointReference http://localhost:8080/jaxws-endpointReference?wsdl' xmlns:wsdli='http://www.w3.org/ns/wsdl-instance'>
<wsam:InterfaceName xmlns:wsam='http://www.w3.org/2007/05/addressing/metadata' xmlns:wsns='http://org.jboss.ws/endpointReference'>wsns:Endpoint</wsam:InterfaceName>
<wsam:ServiceName EndpointName='HelloPort' xmlns='' xmlns:wsam='http://www.w3.org/2007/05/addressing/metadata' xmlns:wsns='http://org.jboss.ws/endpointReference'>wsns:EndpointService</wsam:ServiceName>
</Metadata>
</EndpointReference>

and process it with the following code:

StreamSource source = new StreamSource(new StringReader(XML_SOURCE));
EndpointReference epRef = EndpointReference.readFrom(source);
printXml(epRef.toString());

the output will be (should be identical)

<?xml version='1.0' encoding='UTF-8'?>
<EndpointReference xmlns='http://www.w3.org/2005/08/addressing'>
<Address>http://localhost:8080/jaxws-endpointReference</Address>
<Metadata wsdli:wsdlLocation='http://org.jboss.ws/endpointReference http://localhost:8080/jaxws-endpointReference?wsdl' xmlns:wsdli='http://www.w3.org/ns/wsdl-instance'>
<wsam:InterfaceName xmlns:wsam='http://www.w3.org/2007/05/addressing/metadata'>wsns:Endpoint</wsam:InterfaceName>
<wsam:ServiceName EndpointName='HelloPort' xmlns:wsam='http://www.w3.org/2007/05/addressing/metadata'>wsns:EndpointService</wsam:ServiceName>
</Metadata>
</EndpointReference>

As you can see xmlns:wsns namespace declaration is lost during the identity process
