MP Rest client don't work correctly with CompletionStage and RX data types. Client application freezes.
Example
REST API:
@Path("/") public interface RxTestInterface { @GET @Path("normal") Single<String> normalSingle(); @GET @Path("normal") String normalString(); @GET @Path("normal") CompletionStage<String> normalCs(); }
End-point:
@Path("/") public class Resource { @GET @Path("normal") public String normal() { return "resteasy"; } }
Client code (proxy works correctly):
public class App { public static void main(String[] args) throws Exception { ResteasyClient client = (ResteasyClient) ClientBuilder.newBuilder().build(); RxTestInterface proxy = client.target("http://127.0.0.1:8080/jaxrs-wf").proxy(RxTestInterface.class); CompletionStage<String> cs = proxy.normalCs(); System.out.println(cs.toCompletableFuture().get()); Single<String> single = proxy.normalSingle(); single.subscribe((String s) -> { System.out.println(s); }); client.close(); } }
Client code (MP without CompletionStage and RX works correctly):
public class App { public static void main(String[] args) throws Exception { RxTestInterface mpRestClient = MicroprofileClientBuilderResolver.instance() .newBuilder() .baseUrl(new URL("http://127.0.0.1:8080/jaxrs-wf")) .build(RxTestInterface.class); String s = mpRestClient.normalString(); System.out.println(s); } }
Client code (MP with CompletionStage or RX freezes - client application never ends):
public class App { public static void main(String[] args) throws Exception { RxTestInterface mpRestClient = MicroprofileClientBuilderResolver.instance() .newBuilder() .baseUrl(new URL("http://127.0.0.1:8080/jaxrs-wf")) .build(RxTestInterface.class); CompletionStage<String> cs = mpRestClient.normalCs(); System.out.println(cs.toCompletableFuture().get()); Single<String> single = mpRestClient.normalSingle(); single.subscribe((String s) -> { System.out.println(s); }); } }
