> producerPerformance system test for old client failed after v3.5.0

> Key: KAFKA-15239
> URL: https://issues.apache.org/jira/browse/KAFKA-15239
> Project: Kafka
> Issue Type: Test
> Components: system tests
> Affects Versions: 3.6.0
> Reporter: Luke Chen
> Assignee: Federico Valeri
> Priority: Major
> Fix For: 3.6.0
>
>
> While running producer performance tool in system test for old client (ex:
> quota_test), we will try to run with the dev-branch's jar file, to make sure
> it is backward compatible, as described
> [here|https://github.com/apache/kafka/blob/trunk/tests/kafkatest/services/performance/producer_performance.py#L86-L88],.
> {code:java}
> # In order to ensure more consistent configuration between versions, always
> use the ProducerPerformance tool from the development branch {code}
>
> But in KAFKA-14525, we're moving tools from core module to a separate tool
> module, we're actually breaking the backward compatibility. We should fix the
> system test. Also maybe we should also mention anywhere about this backward
> compatibility issue?
> Note:
> This is the command run in system test. Suppose it's testing old client 3.4.0
> (file put under `~/Downloads/kafka_2.13-3.4.0` in my env), and running under
> the latest trunk env.
