Ekaterina Dimitrova commented on CASSANDRA-18688:
-------------------------------------------------
bq. This was almost ready. Is anything pending I am blocking as a reviewer?
I see an ongoing discussion between [~skokoori] and [~mck] in regard:
bq. -J option is inline with -R, f etc. we already provide for bin/cassandra.
By env var, I assume you mean something like what we had to enable JDK11 in
4.x, with a -D.
I am still not clear on which of the two options we go for:
bq. The options after this patch are:
1) Leave it that way and add the J flag only for 17+ if anyone wants to run
Cassandra experimentally on any of the newer versions.
2) Change it to the J flag suggested (same as 17+). Reject running on those
versions in general, give the people the chance to run Cassandra experimentally
on version 11-17 and 17+ by using the J flag
Also, [~skokoori] is off these days
> Limit Java runtime in 5.0 to JDK 11 and 17 in scripts; add a flag to opt out

> Currently, we limit our users from building with non-default Java versions in
> build.xml.
> They can easily hack build.xml for test purposes with different versions.
> Cassandra–5.0 will be run on JDK11 and JDK17, but on startup, we do not limit
> people to those two, but only to everything >= 11. We should also put an
> upper limit of 17 in our Cassandra startup scripts. We can also add a flag to
> opt-out if someone wants to test with newer versions.
