Ben Manes commented on SOLR-9284:
---------------------------------
Hopefully I didn't break this behavior when upgrading from
ConcurrentLinkedHashMap (Caffeine's predecessor). That code used an eviction
listener, so I think it was a direct translation. Can you take a look and see
if the prior version was more correct?
Note that the cache, in its current form, will only evict after the maximum
size threshold is crossed. However, Guava does evict prior due to being split
into multiple segments that are operated on exclusively during a write. I kept
that wording in the JavaDoc to provide flexibility, just in case.

> grow indefinitely.
