Transaction getCurrentTransaction()
     At any given moment there can be several transactions running in the thread. On of possible implemetations can have stack of nested trasactions associated with a thread. Only one of them is active at any given moment.
boolean hasCurrentTransaction()

void release(Transaction transaction)
     Return transaction to the pool if needed. Necessity of this method is questionable since w/o commit or rollback on update it can cause dead locks.
void releaseUnchecked(Transaction transaction)
     Return transaction to the pool if needed. Necessity of this method is questionable since w/o commit or rollback on update it can cause dead locks.
void rollback(Transaction transaction)

void rollbackSilently(Transaction transaction)
     Rollback transaction and return it to the pool if needed.
void rollbackUnchecked(Transaction transaction)

void shutdown()
