HQL for one-to-one associations is not fully bi-directional
-----------------------------------------------------------

                 Key: HHH-5021
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5021
             Project: Hibernate Core
          Issue Type: Bug
          Components: core, query-criteria, query-hql
    Affects Versions: 3.3.2
            Reporter: Fol De Rol


Let's assume we have two entities A and B mapped to each other with a bi-directional one-to-one association. Let A.b and B.a are appropriate linked attributes, and A owns the association. Let's try the following HQL queries:

1. from A where b is null
2. from B where a is null
3. from B where a.b is null

Query 1 works correctly.
Query 2 produces a wrong SQL expression.
Query 3 works, though produces a redundant SQL query.

My opinion is that query 2 should also be valid.
