* Adapter for a JTA UserTransaction handle, taking a JTA
* {@link javax.transaction.TransactionManager} reference and creating
* a JTA {@link javax.transaction.UserTransaction} handle for it.
*
* The JTA UserTransaction interface is an exact subset of the JTA
* TransactionManager interface. Unfortunately, it does not serve as
* super-interface of TransactionManager, though, which requires an
* adapter such as this class to be used when intending to talk to
* a TransactionManager handle through the UserTransaction interface.
*
*
Used internally by Spring's {@link JtaTransactionManager} for certain
* scenarios. Not intended for direct use in application code.
