Re: [hibernate-announce] [hibernate-dev] Hibernate ORM 4.1.1 release - Undocumented behavior change in Optimistic Versioning ?

by Steve Ebersole

Indexed collections (maps and lists) should always be the owning side of bi-directional associations for the exact reason you mention. Not sure if annotations actually enforces that or whether JPA even allows us to enforce that.
