I'm fuzzy myself, but the idea is that any asynchronous action that will be completed in the future should be represented by a CompletableFuture. In this case, the asynchronous actions are performed by the GC. I imagine an API on e.g. WeakReference CompletableFuture<Void> whenCleared() and then a user can schedule follow-on actions in the executor of their choice. WeakReference r = ... r.whenCleared().thenRunAsync(...) One idea is to throw away as much Cleaner machinery as possible to reuse CompletableFuture machinery. Or build on top... All concurrency machinery is hard for humans to understand.
