[~smiklosovic], I have to apologize to you! There is a typo in your name in the
commit message, and I did not notice it before committing it. "I" and "o" are
next to each other on the keyboard...
I will be more careful in the future!

Thank you both for the reviews!

I verified that it does not throw that exception anymore on Java 17 so I am +1
in that regard. TOTAL_CAPACITY change makes sense to me as well.

5.0 Patch PR: https://github.com/apache/cassandra/pull/2683
5.0 JDK17 green CI run:
https://app.circleci.com/pipelines/github/ekaterinadimitrova2/cassandra/2512/workflows/450638d5-873e-4257-824b-0db189236615
Also, tested locally and verified the debug log, no more exceptions are thrown.
I believe we can safely propagate the patch to trunk and do only local check,
saving on resources for full CI run.
I also used the opportunity to clean a few lines of dead code JDK8 related.
TOTAL_CAPACITY had a different name in JDK8 so we were checking for that one in
case we are on JDK8, but we dropped it already for 5.0+.
[~mck] , do. you mind to review this one? Seems like you worked on
TOTAL_CAPACITY issue when we were upgrading to JDK11.
