> The following sample code snippet may yield a OptimisticLockException.
> Query tc_query =
> itemManager.createNamedQuery("TypeCategory.find_tc").setParameter("product_id",
> new Integer(product_id));
> tc_query.setLockMode(LockModeType.PESSIMISTIC_READ);
> Collection typeCat = tc_query.getResultList();
> This is a incorrect behavior per JPA 2.0 spec:
> public interface Query {
> /**
> * Execute a SELECT query and return the query results
> * as an untyped List.
> * @return a list of the results
> * @throws IllegalStateException if called for a Java Persistence query
> language UPDATE or DELETE statement
> * @throws QueryTimeoutException if the query execution exceeds the query
> timeout value set
> * @throws TransactionRequiredException if a lock mode has been set and
> there is no transaction
> * @throws PessimisticLockException if pessimistic locking fails and the
> transaction is rolled back
> * @throws LockTimeoutException if pessimistic locking fails and only the
> statement is rolled back
