Anthony, please make sure the JSR 236 spec is clear that tasks/threads
have the same ability to use transactions that the component submitting
them does. For example, they can call transactional enterprise beans,
they can call managed beans that use the @Transactional interceptor,
they can start their own transactions using UserTransaction, etc.
