Wildfly9 @Observes Consumer<Object> bug?

[arkadyn]

When I run localhost:8080/app/res/observer browser is 'working' waiting for answer but it never comes.

It is like fired object is not caught by Observes.

It is working on Glassfish without any problems.

So, is it WF bug or I missed something?

@Path("observer")

public class Test {

    @Inject

    Event<Consumer<Object>> event;

    @GET

    public void getResult(@Suspended AsyncResponse response) {

        Consumer<Object> consumer = response::resume;

        event.fire(consumer);

        Logger.getLogger(this.getClass().getName()).info("getResult() called");

    }

}

@Singleton

public class Helper implements Serializable {

    @Resource

    ManagedExecutorService mes;

    public void observer(@Observes Consumer<Object> consumer) {

        Logger.getLogger(this.getClass().getName()).info("observer() called " + consumer.toString());

        Supplier<String> supplier = this::info;

        try {

            CompletableFuture.supplyAsync(supplier, mes).thenAccept(consumer).get();

        } catch (InterruptedException | ExecutionException e) {

            Logger.getLogger(this.getClass().getName()).info(e.getMessage());

        }

    }

    public String info() {

        return "Just testing";

    }

}

@ApplicationPath("res")

public class JAXRSConfig extends Application {

    public JAXRSConfig() {

    }

}

Hi ark,

What type of deployment archive do you have? is it war? It looks little bit suspicious at least from CDI perspective. Do you have beans.xml file in your deployment and if so what's the content? Can you provide some reproducing app by any chance?

[arkadyn]

Yes, this is war archive, and yes I have beans.xml with bean-discovery-mode="all". I've tried it as EJB or CDI bean.

You can easliy reproduce this by creating a project, these 3 classes, and calling localhost:8080/app/res/observer in web browser.

It works on Glassfish, so from my perspective it is some problem with WF.

But i might be wrong ;)

Hmm, the 'waiting problem' comes up on my WildFly as well

But when I try to run this project on GlassFish Server Open Source Edition 4.1 I get an exception instead:

MultiException stack 1 of 1

org.glassfish.hk2.api.UnsatisfiedDependencyException: There was no object available for injection at SystemInjecteeImpl(requiredType=Event<Consumer<Object>>,parent=Test,qualifiers={},position=-1,optional=false,self=false,unqualified=null,829499833)

Did I miss something?

[arkadyn]

I've just installed fresh copy of Glassfish 4.1 and it works fine for me.

My war package contains those 3 classes, each in separate file, an empty web.xml file

and beans.xml with  bean-discovery-mode="all". Thats all.

All is running on java version 1.8.0_60.

[mayerw01]

Sorry, I've forgotten to change the bean-discovery-mode. It is working in Glassfish now.

Strange, seems that there is some issue with starting the process asynchronous

I don't have much experience with JAX-RS but I am seeing the "waiting" problem on GlassFIsh as well (running on glassfish-4.1-b15-08_30_2015 and jdk 1.8.0_60).

Tomas, as far as I understand build 15 is not officially released (Nightly Build). This might be the cause of your problem.

The latest release should be build 13.
