   fyi, you can set a scheduler thread to expire from the cache regardless of activity. By default the cache relies on user activity to trigger its periodic maintenance. For prompt expiration you can use the JDK9+ provided scheduling thread, e.g. `Caffeine.scheduler(Scheduler.systemScheduler())`. This will then schedule a single task based on the next expiration event in the internal queue. That task will then call `Cache.cleanUp()` to perform maintenance and evict as needed.
