When using stateless session with jdbc batch size we get an

HHH000352: Unable to release batch statement..

error in session.close() after rollback:

Code:
Configuration cfg = new Configuration();
cfg.setProperty(Environment.STATEMENT_BATCH_SIZE, "10");
factory = cfg.configure().buildSessionFactory();

StatelessSession session = factory.openStatelessSession();
Transaction tx = session.beginTransaction();

Employee employee = new Employee("1", "2", 1);
employee.setId(id++);
session.insert(employee);

tx.rollback();

session.close();

In rollback the statements are closed but still remain in the jdbc batch,
which is trying to close them a second time on session.close().

There should not be an error message, since everything is clear up in rollback.
Instead rollback should close the batch too.
