We will need to see the stacktrace and debug details. Caffeine’s loop retries only if the entry was a stale read and once locked is determined to have been already removed from the map. That state transition can only happen in the lock and within a map removal operation. That leaves a small window for a stale read, with the caveat of Map.remove(key). That method discards a refresh, which could block if something weird happened during registration. Since refresh isn’t being used here, I cannot deduce any reason for a bug in Caffeine’s code. As ConcurrentHashMap also loops forever, and was the originally claimed source, we need the details to assess a possible cause. -- This is an automated message from the Apache Git Service.
