@dstepanov can you check this?

[sdelamo]

I think your test is incorrect @CezaryBD you the following code:

@Controller
public class SimpleController {
	@Inject
	SimpleClient simpleClient;

	@Get("/simple-void")
	public Mono<Void> getSimpleVoid() {
		return simpleClient.getSimpleVoid();
	}
}
@Client("http://localhost:6969")
public interface SimpleClient {
	@Get("/simple-void")
    Mono<Void> getSimpleVoid();
}

it is expected that the controller responds 200. Even if the client receives a 204.
