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

Hi all, excuse me if this list isn't indented for such a question, but I asked this question about a year ago in the forums without any answers and I think it should be easy to answer for any Hibernate core developer: According to Hibernate's (3.6.5) reference documentaion (Section 21.1.3, Single-ended association proxies), such a single-ended association proxy can't be constructed by Hibernate if it contains "any final methods". My question is, does this restriction apply to getters/setters of persistent fields only or really to any method in an entity class? As far as I can see Javassist is able to modify final methods as well and even if it were not, why should a method like public final String toString() { return "..."; } prevent Hibernate from using a proxy? Thanks in advance, Robin.
