Hibernate has different regions for caching. If you want to cache a has-many collection, you can (ie the children for class B), but then the class that makes up the collection needs to be Cached as well. Ultimately it comes down to what you need and what you want to cache.

So in your case you could cache any of the classes, and in addition, any of the List's as well. Whether or not it makes sense to do so will probably require some load testing.
