We're coming up on our deployment date, so we're considering our deployment
options (notably, at this point, JBoss and Orion).
The system is running and working under JBoss, and I've been re-porting it
to Orion so that we can do some testing, try and resolve some issues we had
under Orion (for which we got some help from Atlassian that we haven't had a
chance to try out yet). In the process, we've re-adjusted most or all of
the finders, and fixed a few bugs here and there between what JBoss does and
what Orion does. It's been enlightening, as usual.
That said, we've run up against a brick wall. One of our transactional
saves uses a session bean to save two entities in a combined declarative
transaction. Each of these beans can throw validation exceptions when
passed data that's meant to save. We have two unit tests, one which throws
invalid data into the first object, and another which throws invalid data
into the second object.
The second object is relatively easy -- if it has problems, the session bean
sets the transaction to rollback only, and lets the server do the rest of
the work. This works under both Orion and JBoss as expected.
If the first object fails, though, there are larger issues -- we still want
to find out if there's a problem with the data being passed to the second
object. Under JBoss, if we tried to do this in the same transaction, it
complained that the transaction was already rolled back, which is sensible.
So we put the validation method into a 'requires new' transaction. On
JBoss, if the first object fails, the second one tests its data in a new
transaction, gathers the validation errors, and rolls back. On Orion, this
seems to create an exception:
Testcase: testProgramRollback took 4.703 sec

I'm basically unable to diagnose why this error would occur. Does anyone
have any suggestions?
