> NPE when sending REQUEST_RSP from 3.0 to 4.0 in in-jvm dtests
> -------------------------------------------------------------

> Key: CASSANDRA-15946
> URL: https://issues.apache.org/jira/browse/CASSANDRA-15946
> Project: Cassandra
> Issue Type: Bug
> Components: Test/dtest
> Reporter: Jacek Lewandowski
> Assignee: Jacek Lewandowski
> Priority: Normal
>
> There is a communication problem when testing upgrades using in-JVM dtest
> between Cassandra 3 and 4.
> In a method {{registerInboundFilter}} of {{Instance}}, we get a message which
> was just received and we prepare it for filtering as part of which, we
> serialize the payload again. This is fine when dealing with incoming
> Cassandra 4 message, because we can serialize it. However when we get the
> Cassandra 3 message, which uses a different protocol, and we get something
> like {{REQUEST_RSP}}, we can surely deserialize it through some special
> deserialization path, but we cannot serialize the payload for it as there is
> no serializer defined for {{REQUEST_RSP}} - no wonder, why would Cassandra
> 4.0 need to be able to serialize Cassandra 3.0 payloads?
