Yonik Seeley commented on SOLR-10121:
-------------------------------------
I reviewed the pertinent BlockCache and couldn't see any thread safety issues.
Looking at the history of BlockCache, I reverted to right before SOLR-7355 was
applied, and the issues went away. So it looks like a thread safety or usage
issue with Caffeine?
[~ben.manes], does putting a key/value in Caffeine constitute safe publication
to a different thread (as is the case with ConcurrentHashMap for example)?
