Maybe due to downstream got result earlier than completionFuture at https://github.com/line/armeria/blob/0d94d0df85ba9b1184c79ffdd58d3e414b2f0c7d/core/src/main/java/com/linecorp/armeria/common/stream/InputStreamStreamMessage.java#L374-L380.I think it's ok to just add awaitility to wait for open is false case.
