It's possible; I don't use Spring, so I can't really say. I know that in
EJB 3.1 container managed transactions with JTA data sources the
guarantees are strong:

- If the exception thrown is annotated @ApplicationException then
rollback is controlled by that annotation; otherwise:

- If it's an unchecked exception, the transaction is rolled back; and

- If it's a checked exception that's properly declared the transaction
is NOT rolled back

I don't know what Spring's rules are. It's all a bit localized and
specific to your code, so it's difficult to offer any useful advice at
this point.

If there's any chance you can cook it down to a small, runnable,
self-contained test-case that'd be very useful. In my experience when
I've done so I have, in the process, often found a bug in my code that
was the cause of the problem. When I don't find an issue in my code I
usually have something clear that demonstrates a problem and helps
isolate which project(s) the problem is in.
