      Description

      When creating a gzipped MessageSet, the collection of Messages is passed to CompressionUtils.compress(), where each message is serialised [1] into a buffer (not just the payload, the full Message with headers, uncompressed), then gripped, and finally wrapped into another Message [2].

      In other words, the consumer has to unwrap the Message flagged as gzipped, unzip the payload, and unwrap the unzipped payload again as a non-compressed Message.

      Is this double-wrapping the intended behaviour?

      [1] messages.foreach(m => m.serializeTo(messageByteBuffer))

      [2] new Message(outputStream.toByteArray, compressionCodec)
