> The JAXB Marshaller code is generating bad xml in intermittent situations.
> Specifically, an xmlns:xmlns is being written in the root element of the JAXB emission.
> Stack Dump = org.apache.axis2.AxisFault: javax.xml.stream.XMLStreamException: The namespace prefix "xmlns" must not be declared.; nested exception is: 
> 	org.apache.axiom.om.OMException: javax.xml.stream.XMLStreamException: The namespace prefix "xmlns" must not be declared.
> 	at org.apache.axis2.transport.http.HTTPTransportUtils.processHTTPPostRequest(HTTPTransportUtils.java:284)
> Solution Proposal:
> Current code:
>     JAXB Marshaller ---->  Woodstox XMLStreamWriter
> New code:
>     JAXB Marshaller -----> XMLStreamWriterFilter ----> Woodstox XMLStreamWriter
> This filter will detect the erroneous xmlns:xmlns and swallow it (with logs).
> We can use the logged information to open a formal defect against JAXB.
> P.S.  This filter is only installed specifically for JAXB marshalling in the JAXWS code.  It is not a general purpose filter.
