> 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.
