		if (fetchPlan instanceof JDBCFetchPlan) {

			((JDBCFetchPlan) fetchPlan).setIsolation(isolation);
		}
	}

	entityManager.getTransaction().begin();

	if (!definition.isReadOnly()) {
		// Like with EclipseLink, make sure to start the logic transaction early so that other
		// participants using the connection (such as JdbcTemplate) run in a transaction.
		openJpaEntityManager.beginStore();
	}

	// Custom implementation for OpenJPA savepoint handling
	return new OpenJpaTransactionData(openJpaEntityManager);
