> Core cache keys are typically used for caching, for instance we use them in the query cache and when uninverting.
> However, since FilterLeafReader delegates addCoreClosedListener by default, these listeners will always be called with the cache key of the wrapper reader. So if you happen to use a filter reader that overrides the core cache key, you are going to try to evict on a different key than the one that you used for caching.
> We should ensure that core closed listeners are always called on the same key as the one returned by #getCoreCacheKey
