Ekaterina Dimitrova commented on CASSANDRA-17909:
-------------------------------------------------
The SyncUtil class was updated for JDK11 and 17.
Notable changes:
* old Java 7 and 8 code was removed. This effectively makes this patch commit
blocked on CASSANDRA-18255
* We should not be throwing any more UnsupportedOperationException
[here|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/utils/SyncUtil.java#L126-L127].
[This|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/utils/SyncUtil.java#L125]
comment is not applicable anymore since [this
fix|https://github.com/openjdk/jdk11u-dev/commit/a7b3a19ec476e31d08146628fe51a4b107086c78]
fix in JDK11.
I suspect we want to port a minimal fix for JDK11 on previous branches, but
let's see first whether my trunk patch will be accepted.
[trunk PR|https://github.com/apache/cassandra/pull/2456],
[CI|https://app.circleci.com/pipelines/github/ekaterinadimitrova2/cassandra?branch=17909-trunk]
I can see only the known failures from the table in CASSANDRA-16895 in CI.
[~jlewandowski], could you review this one?
