> Those old Kafka versions don't support JDK17. You need to run them with jdk8. Pardon me, is there any other issue, aside from [ZOOKEEPER-3779](https://issues.apache.org/jira/browse/ZOOKEEPER-3779), that prevents Kafka versions [2.1, 2.2, 2.3] from running on JDK 17? > ZK 3.5.7 is not compatible with Kafka 2.1 Please read [KIP-902](https://cwiki.apache.org/confluence/display/KAFKA/KIP-902%3A+Upgrade+Zookeeper+to+3.8.2) Do you mean Kafka versions [2.1, 2.2, 2.3] can't use the ZooKeeper 3.5.7 client? If so, I didn't see that mentioned in KIP-902. Additionally, it seems that PR #6802, which upgraded ZooKeeper from 3.4.x to 3.5.x, didn't change the use of ZooKeeper APIs (except for running the ZooKeeper main, which is unrelated to the E2E compatibility test we're discussing). --- It seems to me that the root cause is the `ZK 3.4.x client`, which can't run under JDK 17 and `ZK 3.8.x server`. That's why I plan to replace the `ZK 3.4.x client` JAR with the `ZK 3.5.x client` JAR for Kafka versions [2.1, 2.2, 2.3] in E2E tests. This change would allow us to run the E2E tests under JDK 17 with a ZK 3.5+ server. -- This is an automated message from the Apache Git Service.
