The domain object is actually an annotated ejb3 entity bean. It's a pretty
simple one with just the usual few member variables and annotated
getters/setters. As I stepped through the code, as far as I can tell it
finds the class and seems to look at the
javax.persistence.Entityannotation and then somewhere after that it
dies with the
NullPointerException. I'll send the code through later as it's on my machine
at home although I'm guessing it should be easy to reproduce with a
lightweight ejb3 annotated entity bean.
