No, there's nothing like that. I think you're right: from the point where the reference is assigned to the referent field of the WeakReference it is only reachable by traversing a weak reference, therefore it is weakly reachable. Adding the reachabilityFence would not hurt anything, and if it did make a difference to generated code it'd eliminate a bug. There may be a few more of these. Andrew.
