------------------------------------
Summary: Core closed listeners should be called with the same
cache key as the one returned by getCoreCacheKey
Key: LUCENE-6483
URL: https://issues.apache.org/jira/browse/LUCENE-6483
Project: Lucene - Core
Issue Type: Bug
Reporter: Adrien Grand
Assignee: Adrien Grand
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
