David Capwell commented on CASSANDRA-15556:
-------------------------------------------
I’ll have to double check /lib; thought ant would pull it...
I kept it a isolated class just in case it does crash. When the jvm crashes in
CI we loose all test results and only know about the crash.
Is sstable impacted? Unknown and believe not to be as of the Jira I linked.
Should it switch? I rather leave that for another Jira to tackle :)
