public class OnUpdateVisitor
extends ReattachVisitor
When an entity is passed to update(), we must inspect all its collections and
1. associate any uninitialized PersistentCollections with this session
2. associate any initialized PersistentCollections with this session, using the
existing snapshot
3. execute a collection removal (SQL DELETE) for each null collection property
or "new" collection
