Steve Ebersole commented on HHH-5275:
-------------------------------------

The developer meeting is held on IRC, #hibernate-dev on freenode.  You just have to be a registered freenode user.

I understand what you want.  But as a developer I am sure you also understand the unworkability of maintaining bug fixes for all versions you have ever released.  Thats simply not scalable.  We would do nothing else ever but backport fixes between our various release branches.

> The LockMode set via Criteria.setLockMode does not generate a ' for update' SQL statement. In the org.hibernate.dialect.Dialect class only the LockOptions are used for determining a possible addition to the SQL statement if using pessimistic locking. This behaviour is different from Hibernate 3.1.3.
> In the supplied TestCase two threads are reading the same database record; one of those threads should use pessimistic locking thereby blocking the other thread. But both threads can read the database record causing the test to fail.
