We're working on a patch. In the meantime, please just copy and paste
your field mappings from the abstract class mapping into the contrete
class mapping. And comment out
the abstract class mapping.
This is a limitation of sharing the MappingLoader with Castor JDO, as
they do
not allow abstract classes, but Castor XML does. Once we get it resolved
we'll let you know.

This might be a resonable approach. I've submitted a patch to the JDO
team for
review.

Yes, absolutely. Actually, I was under the impression this was already
fixed. But apparently it's not. We'll have it cleaned up ASAP.
