OK, so the reason we now throw InactiveTransactionException is because (as the JIRA
states) IllegalStateException has a well defined meaning according to JTA "Thrown if
the current thread is not associated with a transaction." In this case there is a
transaction associated with the calling thread, it's just that it's no longer
active. OTS correctly differentiates these cases, but once again JTA is broken in this
regard ;)
So what we did was provide a new SystemException to try to allow for the differentiation
in the case someone codes against our specific exceptions as well as those who don't
care and only catch SystemExceptions (or not). I didn't like the idea of deriving from
IllegalStateException because in the case of users who only catch that exception rather
than, say, an InactiveTransactionException that is derived from ISE, their code may assume
one thing (no transaction) when in fact that's not the case. At least with an
exception derived from SE code cannot make any assumption about the thread-to-transaction
association.
