Derek Chen-Becker commented on CASSANDRA-18027:
-----------------------------------------------
I'm +1 to these changes. For what it's worth, MaxGCPauseMillis is purely
advisory and I'm not sure that the time vs throughput explanation in the
comment is still applicable in JDK17 with the changes that have happened to G1.
Not an objection, just something to note as we continue to update JVM version
support.

> G1GC is well battle tested now, and the recommended configuration for most
> users. CMS can work well on smaller heaps but requires more tuning, initially
> and over time. G1GC just works. CMS was deprecated in JDK 9.
