What I did was I deleted the JAXB jars from the JBoss installation, and I used Java 6, which ships with a built-in JAXB 2, and everthing works fine.
but in my opinion, they should seperate jar files of different packages. so we can easily exclude a jar file and use the alternate jar instead. now the packages packed into a jar file , for example, with the extension name "-all".
Please open JIRA issues for any packaging issues that you run into so that we don't lose track of them.
