-------------------------------------------------------------------------
Gotcha, _python upgrade dtest upgrade_ that are upgrading the jvm during the
test… TIL.
Are there really any tests that switch the jdk during the test…? and if so, why
any longer?
A quick search and I cannot find any such tests, and my vote is on not
recommending to users (or supporting) switch C* versions and JDK version on the
same node restart (Operators should be de-risking by default).

> Update CCM for JDK17 and revise current JDK detection strategy

> Key: CASSANDRA-18106
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18106
> Project: Cassandra
> Issue Type: Task
> Components: CI
> Reporter: Ekaterina Dimitrova
> Assignee: Brandon Williams
> Priority: Normal
> Fix For: 4.x
>
>
> As part of CASSANDRA-16895 initial POC an initial version of CCM patch was
> created. This needs to be revisited and reviewed
> Recently we closed CASSANDRA-18039 which brought questions, probably we need
> to revise how we detect JDK versions in CCM and whether it is correct. To the
> best of my knowledge there are certain tests in the repo around that and they
> pass so my guess is we need to revise just the strategy and maybe document it
> explicitly or consider if we want any changes to be applied. Also, we need to
> be careful with breaking changes.
