[hibernate-dev] Still true with Javassist? Any final method prevents Hibernate from creating single-ended association proxies

If your toString method ends up calling some of the entity state (likely), the initialization won't be triggered since you will call your getters from inside the instance. So it's a good general rule to mandate non final methods on entities.
