Roadmap

Unscheduled yet

• Implement LogLess Transactions optimization, see: http://blogs.sun.com/fkieviet/entry/logless_transactions.
• Implement a generic XAResourceHolder that calls public XAResource getXAResource() via reflection on some passed-in object. This should allow manual enlistment of any kind of resource, not just JDBC and JMS.
• Implement JTA 1.1 (TransactionSynchronizationRegistry).
• Implement XATerminator, this will allow BTM to support propagation of the transactional context to/from another JVM.
• Add support for JCA.
