Seems like a reasonable alternate approach, however I think there ought to be a way to clear the reference as well,

Do you have a use case?

If we wanted to support removals (I don't think we should), I would do something like this:

public class ClassLoader { public Reference<?> keepReferenceTo(Object o) { ... } ... }

You could call clear() on the returned reference to clear the ClassLoader's reference. Internally, it would use some sort of CAS doubly-linked list.
