This really is weird.  Where is your DatatypeConverterImpl coming from?
java -verbose:class will tell you.  I think you've got some sort of mix
of classes from implementations.

This is a private class that's part of Sun's JAXB.

It seems to me that you aren't really running gcj.  Simply changing
JAVA_HOME doesn't control which Java you're using.
