It is NOT a logical extension of what I'm saying. I'm saying that
non-trivial finalizers should always include a call to super.finalize().
In "contract-oriented" programming more generally, every method
that overrides another should super-call the latter. (The
langauges Simula67 (the first object-orineted language) and BETA
enforce this by turning this around: Instead of a overriding
method calling super, the base methiod calls INNER to call the
overriding method.)
It does NOT follow that every class should have a finalizer.
Ok.
Adding a trivial finalizer does NOT help in the event that the
programmer changes the classes position in the class hierarchy.
But having a (previously redundant) super.finalize() call in a
non-trivial finalize method may turn out to be a GOOD THING.
True. I wasn't thinking clearly.
I still don't think it is a good idea reason to call super,finalize
if super is Object - and I don't think we should warn in that case.
