[jira] [Created] (KAFKA-8998) Release Candidate Version 2.3.1-rc1 breaks backward compatibility in PATCH version

Juan Pablo Correa created KAFKA-8998:
----------------------------------------

             Summary: Release Candidate Version 2.3.1-rc1 breaks backward compatibility in PATCH version
                 Key: KAFKA-8998
                 URL: https://issues.apache.org/jira/browse/KAFKA-8998
             Project: Kafka
          Issue Type: Bug
          Components: clients
    Affects Versions: 2.3.1
            Reporter: Juan Pablo Correa


The expected type for the `preparedResponse` method in the `MetadataResponse` ([https://github.com/apache/kafka/blob/2.3.1-rc1/clients/src/main/java/org/apache/kafka/common/requests/MetadataResponse.java#L466]) has changed from a `List<Node>` to a `Collection<Node>` from the version 2.3.0 to 2.3.1, this breaks the backward compatibility that one would expect from a PATCH version.
