It looks like your installation of JAXB or JAXP is inconsistent. I don't
know how it can happen, but the error location is where JAXB is calling
one of JAXP methods, and the AbstractMethodError suggests that somehow
those classes gets out of sync.
Could you reinstall JAXP/JAXB and recheck your classpath to make sure
that you don't have any old ones.
regards,
