'illegal attempt to dereference collection' when using auto-join
----------------------------------------------------------------

                 Key: HHH-2667
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2667
             Project: Hibernate3
          Issue Type: Bug
    Affects Versions: 3.2.4.sp1, 3.2.4, 3.2.3
         Environment: I have found that behaviour in version 3.2.4.sp1 and 3.2.3 (I didn't test 3.2.4 pre sp1)
Database: ORACLE 10g
            Reporter: Martin Kouba


After upgrading to the latest Hibernate version I got this error.

I try to use a statement like this
from cat c where c.mate.id = 13

the expected resulting SQL should be something like
SELECT * FROM CAT C WHERE C.MATE_ID = 13

which is much more performant than making a join
from cat c join c.mate m where m.id = 13

which would result in something like that
SELECT * FROM CAT C INNER JOIN MATE M ON C.MATE_ID = M.ID WHERE M.ID = 13

This works as expected in 3.1.3, 3.2.0 and 3.2.2

It doesn't work with version 3.2.3 and with 3.2.4.sp1.
