      Prepare the following remote service description in the test class:

       @Path("/api/v1") private interface CarRemoteService { @Path("car/metadata") @GET Mono<String> getCarMetadata(); }

      and the following server implementation in a springboot app:

       @RestController @RequestMapping(value = "api/v1", produces = APPLICATION_JSON_VALUE) public class MyRestController { @GetMapping("/car/metadata") String getCarMetadata() { return "metadata"; } }

      Then run the following test:

       @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) class MyRestControllerTest { 
@Value("${local.server.port}") 
private int port; 
private Client client; 

@Path("/api/v1") 
private interface CarRemoteService { 

@Path("car/metadata") 
@GET Mono<String> getCarMetadata(); } 

@BeforeEach 
void setUp() { client = ClientBuilder.newClient(); } 

@Test 
void givenProxyFrameworkAPI_callServerWithMonoBasedClient() { 
ResteasyWebTarget target = (ResteasyWebTarget) client.target("http://localhost:" + port); 

final CarRemoteService carRemoteService = target.proxy(CarRemoteService.class); assertThat(carRemoteService.getCarMetadata().block()).isEqualTo("metadata");

      Given a Java Interface that describes a remote Service using Mono<T> and Flux<T> as method return types, and given that we depend on resteasy-reactor, when calling proxy(Interface.class) and they calling the proper methods on the generated proxy, weird errors about not finding the proper messageBodyReader are shown.
