Maybe you've tried this already but if listeners were changed to be a WeakHashMap<VMListener, Boolean> then this would expunge the stable entries. This would also avoid the O(n) search in removeUnreachableListeners and simplify many other operations. But maybe you are concerned about preserving the insertion order of the listeners? ------------- PR: https://git.openjdk.org/jdk/pull/12081
