Pessimistic Lock not honour when ORDER BY clause is used
--------------------------------------------------------
Key: OPENJPA-1394
URL: https://issues.apache.org/jira/browse/OPENJPA-1394
Project: OpenJPA
Issue Type: Bug
Components: query
Affects Versions: 2.0.0-M3, 2.0.0
Reporter: Albert Lee
Assignee: Albert Lee
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.
