Re: [Hibernate] New error on Annotation query

Max, can you clarify here?  Thinking some more about it, maybe you just
meant the column name discovery (as it should be possible to still
auto-discover types in this scenario)?

Also, in general, we need to make certain that these types of
"integration point tests" are defined within the Hibernate test suite
proper so that we can catch these discrepancies earlier...

Has something changed that I haven't propagated in my code?
