And that it react accordingly? JTS knows nothing about UserTransaction. The closest equivalent is OTS::Current. UserTransaction works on the thread-to-transaction association. Some implementations I've seen give out a thread specific instance of UserTransaction. But the common implementation is one instance that does the multiplexing behind the scenes, so you can share the same instance between multiple threads.
