In this case, if the WeakReference cannot be reached from some other root, its semantics are void. Note that initially the WeakReference refers to the queue not the other way around. Reference processing occurs from the roots and conditionally gaining semantics when traversing through Reference objects. So at least until the weakly-reachable condition is satisfied the WeakReference must be reachable from another (strong) root. https://docs.oracle.com/en/java/javase/18/docs/api/java.base/java/lang/ref/package-summary.html#reachability ------------- PR: https://git.openjdk.org/jdk/pull/9649
