/**
* A simple {@link TransactionManager} implementation.
*
* It provides the basic to handle {@link Transaction}s and supports any {@link javax.transaction.xa.XAResource}.
*
* Implementation notes:
- The state is kept in memory only.
- Does not support recover.
- Does not
* support multi-thread transactions. Although it is possible to execute the transactions in multiple threads, this
* transaction manager does not wait for them to complete. It is the application responsibility to wait before invoking
* {@link #commit()} or {@link #rollback()}
- The transaction should not block. It is no possible to {@link
* #setTransactionTimeout(int)} and this transaction manager won't rollback the transaction if it takes too long.
*
*
* If you need any of the requirements above, please consider use another implementation.
*
* Also, it does not implement any 1-phase-commit optimization.
*
* @since 14.0
