Perhaps add watches and verify the following events triggered:
- DataWatchRemoved
- ChildWatchRemoved

I guess it might be particular important to test this as ZooKeeper.removeWatches is cheating since ZOOKEEPER-1910. See also kezhuw/zookeeper-client-rust#2.

@kezhuw I agree that it can be a bug as I mentioned in https://lists.apache.org/thread/0kcnklcxs0s5656c1sbh3crgdodbb0qg. You can reply on the mailing list and file an issue.
