JBossWS Client sending a transfer object containing javax.xml.transform.Source as an mtom attachment is adding null (\0) bytes at the end of the message. When the WS on the server side pulls the Source out and tries to transform it, it throws this exception: javax.xml.transform.TransformerException: org.xml.sax.SAXParseException: Content is not allowed in trailing section.
