Adding more then one GrpcService causing warnings for each endpoint

See original GitHub issue

    server = Server.builder()
      .http(port)
      .service(GrpcService.builder()
        .addService(new GreeterImpl())
        .addService(new RouteGuideImpl())
        .build())
      .build()

This simple code triggers warnings

21:52:08.601 [main] WARN  com.linecorp.armeria.server.ServerBuilder - The service that you are trying to add with 'serviceUnder' has multiple routes, but its routes will be ignored and it will be served under '/routeguide.RouteGuide/ListFeatures': service=com.linecorp.armeria.server.grpc.FramedGrpcService@c3edf4c

I believe this was introduced by this change: https://github.com/line/armeria/pull/3786

Service are working but now Armenia is a bit noisy and misleading.

You didn’t use serviceUnder(“/”, …), right?

I think he didn’t use serviceUnder("/", ...). 😅 I have confirmed that there’s a bug. 😅 We should fix that.

Hi @octo47

if I use http transcoding and serveUnder(“/”…) it doesn’t work.

That’s why I added the warning message.

The service itself built from GrpcServiceBuilder has multiple HTTP/JSON routes and the routes can be registered only with the following two methods:
