> query = em.createQuery(
> "select e.department from Employee e where e.id < 10 order by
> e.department.id").setFirstResult(3);
> query.setLockMode(LockModeType.PESSIMISTIC_READ);
> q = query.getResultList();
> yields the following SQL statement but with no lock on the Employee row:
> openjpa.Runtime: Info: The database is unable to lock this query. Each
> object matching the query will be locked individually after it is loaded;
> however, it is technically possible that another transaction could modify the
> data before the lock is obtained. See the documentation on Object Locking
> for details.
