Hi Mickael,
I did the following steps:=
1. Built from source JDK 17
2. Validated all keys, checksums, and signatures
3. Ran unit tests
4. Ran the following quick starts
1. Kafka
2. docker apache/kafka and apache/kafka-native images
3. Connect
4. Kafka Streams
5. Spot checked the Java doc
+1(binding)
Thanks,
Bill
