reply to @dholmes-ora comment:
> I think a better design for the classes that can't extend FinalizableObject would be for them to contain a FinalizableObject, the cleanup action for which would cleanup the host object. That could allow the removal of the Finalizable interface and simplify the general usage patterns. But that may be going too far for this particular PR ... ?

We still need the `Finalizable` interface to call the `cleanup` of the host object:

class FinalizableObject implements Finalizable { 
 public void registerCleanupForObject(Finalizable obj) { 
  Cleaner.create().register(obj, obj->cleanup()); 
}
