Fixes KAFKA-21302 With `group.protocol=streams`, a member with identical copartition constraints can be rejected because of differences in source topic ordering. For example, constructing the same join with source topics `["A", "B"]` and `["B", "A"]` can produce heartbeat copartition indexes of `[0, 1, 2]` and `[1, 0, 2]`, respectively. The coordinator compares these lists in an order-sensitive manner and treats the second member’s request as a topology change. It returns `INVALID_REQUEST`, causing the client to transition to FATAL and preventing an otherwise valid instance from joining or replacing an existing member -- This is an automated message from the Apache Git Service.
