[cdi-dev] Bean discovery question

[John Ament]

So I just tried locally with Weld 3.0 CR2


public class BeanDiscoverer implements Extension {
    public void onBeans(@Observes ProcessBean<?> pb) {

    }

    @Singleton
    public static class Producers {

    }

    public static void main(String...args) {
        final SeContainer initialize = SeContainerInitializer.newInstance().initialize();
        final Producers producers = initialize.select(Producers.class).get();
        assert producers == null;
        initialize.close();
    }
}




And it correctly throws


Exception in thread "main" org.jboss.weld.exceptions.UnsatisfiedResolutionException: WELD-001334: Unsatisfied dependencies for type Producers with qualifiers

Even when I explicitly add the extension, same thing occurs (.addExtensions(BeanDiscoverer.class)).  Even when I explicitly add to META-INF/services/Extension it fails.


This is what my beans.xml looks like:


<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee" bean-discovery-mode="annotated" version="2.0">
</beans>


Only when I change to all does it run fine...  You can see the full example at https://github.com/johnament/cdi-2.0-presentations/blob/master/cdi2conference/src/main/java/ws/ament/cdi/se/extensions/BeanDiscoverer.java so I'm curious to know if there's anything different between our setups.

SE, and the initializer is brain-dead simple.

final SeContainerInitializer initializer = SeContainerInitializer.newInstance();
assert initializer != null;
try (final SeContainer container = initializer.initialize()) {
  assert container != null;
}

Since you're mentioning a fledgling project and CDI 2.0, are you using SE mode of CDI, or is this within a container (and I'm guessing some custom integration)?  If you're using SE, what does your SEContainerInitializer lines look like?

Weld version? Environment? Deployment structure?

3.0.0-CR2 (CDI 2.0-PFD).
Fledgling project containing only the extension at the moment, so no beans.

I think the Producers class should not be discovered. So it looks like a
bug or misconfiguration.

Thank you; I'll file a bug once I have time to put together a test case.

Best,
Laird
