Adrien Grand updated LUCENE-6483:
---------------------------------
Attachment: LUCENE-6483.patch
Here is a patch: it changes FilterLeafReader to wrap the CoreClosedListener if
necessary in order to call them on the right core cache key.
> Core closed listeners should be called with the same cache key as the one
> returned by getCoreCacheKey

>
> 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
