No idea.  That exception is coming from down deep in JAXB.  Thus, it's 
something related to the JAXB things, but I really wouldn't know where to 
start looking.  :-(

You could try updating to CXF 2.2.10 (or 11 which is being voted on now) which 
included a much newer version of JAXB.   That may help.
