one-to-one associations inside joined-subclasses don't work

I don't have time to dig through and try to figure out how Hibernate's test cases are structured. The stack trace may be long, but it's not like you have to read the whole thing. Below is the important part. Is that better? Basically when I invoke IMetric.getId() a ClassCastException is being thrown by CGLIB.

I did spend a long time debugging this, and I have fully isolated the problem: one-to-one associations in joined-subclasses don't work. Just because I didn't require a toy example of the problem doesn't mean that I didn't isolate is. I switched to a many-to-one association and the problem was gone, so the one-to-one association has to be the problem.
Rick Hightower ran into a similar issue when he accidentally specified a second ID attribute in a joined-subclass. Here is an account of his error:
http://www.jroller.com/comments/RickHigh/home/hiberante_3_annotations_code_sample
He got a ClassCastException having to do with joined subclasses and ID attributes and the error I encountered also has to do with joined subclasses and ID attributes. In Rick's case he specified something incorrectly. In my case I specified everything correctly but got an error. The two situations are certainly different but they bear a striking resemblence. I'm thinking the key here is the ClassCastException that's occurring in CGLIB when attempting to read the ID attribute of the joined-subclass. I'm guessing the problem is that the one-to-one association is confusing Hibernate so that it thinks the JoinedSubclass is a RootClass instead.
Sorry for not constructing a full test case for you, but if that really is the issue I'm thinking it will be trivial to fix.

Note that org.hibernate.test.onetoone.joined is a good exqample of how this functionality does work under normal circumstances.

Are you serious? I am supposed to believe there is a bug in Hibernate on the basis of a 300-line long stack trace that you have obviously not seriously tried to simplify and debug?
Try resubmitting once you
have simplified your problem down to bare bones and reproduced in a trivial unit test
are able to submit this trivial runnable test case to JIRA
One-to-one associations contained within a joined-subclass don't work. I was able to fix the stack trace by switching to a many-to-one association.
