Jari Juslin commented on HHH-4281:
----------------------------------
The worst thing is, because of the join, the children are always retrieved from DB, even
when they are already in cache..
@ManyToMany appears to ALWAYS generate a left outer join SQL
------------------------------------------------------------
Key: HHH-4281
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-4281
Project: Hibernate Core
Issue Type: Bug
Components: annotations
Reporter: Barry Davies
Priority: Minor
Attachments: files.zip
A collection mapping created using the @ManyToMany JPA annotation appears to create a
left outer join SQL regardless of whether the joinColumn or inverseJoinColumn are marked
nullable or not. This might be in error. Emmanuel asked for a JIRA issue to be created,
so here we are. I have attached some files that can recreate what I believe to be the
issue.
