ORDER BY with many-to-one association doesn't make an outer join with flag : nullable = true
--------------------------------------------------------------------------------------------

                 Key: HHH-5749
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5749
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.6.0
            Reporter: ghanassia


I would like to react to the following post : https://forum.hibernate.org/viewtopic.php?f=1&t=949719&view=next
Bernard Ligny is right by expected this behiavour :

Extract of topic :
" But this leads me to the following suggestion:
I was wondering if, with the help of the not-null attribute in my <many-to-one> mapping, Hibernate could not smartly utilize such information in order to decide how to translate the implicit join:
- if not-null="true" => translated into a normal join
- if not-null="false" => translated into an outer join "

I think than hibernate will better with this behiavour, for me this is bug to ignore the not-null information in association many-to-one to build SQL request.

Of course is possible to write explictly the outer join, but is it realy the philosophy of hibernate ?
