      Setup an HttpClient pointing to a not found URL

      @RegisterRestClient(baseUri = "http://microprofile-test:8080/")
public interface HelloClient {
    
    @GET
    @Path("/hello/notFound")
    @Produces(MediaType.TEXT_PLAIN)
    @Asynchronous
    @Fallback(fallbackMethod = "fallback")
    CompletionStage<String> getWithFallback();

    default CompletionStage<String> fallback() {
        return completedFuture("Fallback");
    }
}

      And then make a query:

      @Inject
@RestClient
HelloClient hello;
      hello.getWithFallback().thenApply(result -> "Client got: " + result);
      Show

       I have a microprofile HttpClient on Native mode, and also a fallback action configured, then I got the following exception:

      2021-01-18 10:36:17,661 ERROR [org.jbo.res.res.i18n] (executor-thread-1) RESTEASY002020: Unhandled asynchronous exception, sending back 500: java.lang.RuntimeException: Not implemented in native mode
