In InOut mode, when `outBody` is null in the `DefaultExchangeHolder`, `unmarshal` does not touch the Out message on the producer exchange, and `getResponseMessage` returns a fresh empty `exchange.getOut()` as the reply. `reply.getMessage()` returns `getOut()` if `hasOut()` — which would be an empty message, not the "Bye World" body on In. The existing `NettyTransferExchangeOptionTest` avoids this by calling `e.getOut().setBody(...)` explicitly on the consumer side. Can you confirm these assertions pass (i.e., that `reply.getMessage().getBody()` returns `"Bye World"`), and that both tests were failing before this fix? -- This is an automated message from the Apache Git Service.
