        Description

        Reference objects cannot be meaningfully cloned. For example when cloning a WeakReference object that is pending for enqueuing, what state should the cloned reference object be? Should the referent of the newly cloned reference be considered as a strongly reference?

        A new Reference object can be created via its constructor and a newly reference object has no relationship with any existing reference objects with the same referent.

        This proposes not to support cloning of Reference object.
