I don't understand the well formed error. It would seem some error is being swallowed or the schema is trying to be parsed from somewhere invalid rather than mapping to the jaxb model. An empy jboss.xml should parse fine. I added a test to the metadata project which runs as expected with the jboss.xml you show.
