The reason you're not seeing the exception is that ejbStore isn't called
(store isn't processed for entities) until the transaction commits,
which isn't until after the session bean method returns (Unless you put
the 'setData' method in a RequiresNew transaction, which I wouldn't do).
If it is invariant that field2 not be null, assert this (throw
IllegalArgumentException) in 'setData', so that you can catch that
exception in the bean. If field2 can be null according to your
requirements and domain model, then your database is simply wrong, this
is a bug that you should fix and get on with your life.
