David Smiley commented on SOLR-16562:
-------------------------------------

It should be noted that this change also upgraded Protobuf from 3.21.4 to 
3.21.8. This resolves a CVE (great) but it's a very indirect and subtle change 
from upgrading a mere caching library that one would think wouldn't have such 
dependencies.

I observe that our build.gradle references Caffeine in 3 places, 2 of which 
specify Caffeine with transitive=false but not 1, in HDFS.  Consequently, we 
have all these unwanted transitive dependency impacts.  Locally I modified the 
build to specify transitive=false in HDFS and re-generated the versions.lock to 
see the impact.  It decremented some references, lowered some versions (like 
Protobuf), and particularly nice is removed lines from the upper non-test 
section of the file for Kotlin.

> Upgrade to Caffeine 3.1.2
