Control characters like that are illegal in XML. You can read Benson's blog
about it:

Technically, I would consider this a bug in the JAXB marshaller as this should
have thrown an exception at write time, not read time. If you turn on
schema validation on the send side, it might throw an exception, not really
sure.
