Ekaterina Dimitrova commented on CASSANDRA-17992:
-------------------------------------------------
I am not happy with the bellow error that pops up in almost every CI run with
random tests. Not convinced we should silence it similar to other Connection
reset failures. I will look further into it in the new year.

> Upgrade Netty on 4.x(current trunk)
> -----------------------------------
>
> Key: CASSANDRA-17992
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17992
> Project: Cassandra
> Issue Type: Task
> Components: Dependencies
> Reporter: Ekaterina Dimitrova
> Assignee: Ekaterina Dimitrova
> Priority: Low
> Fix For: 4.x
>
>
> I haven't been able to identify from the Netty docs which was the lowest
> version where JDK17 was added but we are about 40 versions behind in netty 4
> so I suspect we better update.
> We need to consider there was an issue with class cast exceptions when
> building with JDK17 with newer versions of netty (the newest available in
> March 2022). For the record, we didn't see those when running CI on JDK8 and
> JDK11. We also need to carefully revise the changes between the netty
> versions.
> Upgrading will cover also a fix in netty that was discussed in
> [this|https://the-asf.slack.com/archives/CK23JSY2K/p1665567660202989] ASF
> Slack thread.
