> When a hierarchy of EJBs is looked up via {{Inject Instance}} for an interface that the toplevel ejb implements, lower-hierarchy EJBs (below an {{abstract}} class) are not found unless they (redundantly) reimplement the interface, when Weld is using view proxies.
> In more Detail:
> {code}
> public interface A extends Serializable {}
> ...
> @Stateless
> public class A1 implements A {
> 	public A1() {
> 	}
> }
> ...
> public interface B extends A {}
> ...
> @Stateless
> public class B1 implements B {
> 	public B1() {
> 	}
> }
> ...
> public abstract class C implements A { }
> ...
> @Stateless
> public class C1 extends C {
> 	public C1() {
> 	}
> }
> ...
> @Stateless
> public class C2 extends C implements A {
> 	public C2() {
> 	}
> }
> ...
> public class WeldProcessortInjectionProblemTest {
> 	
> 	@Inject @Any Instance<A> testinstances;
> 	@Test
> 	public void testSubclassInjection() {
> 		boolean foundC1=false, foundC2=false;
> 		for (A a : testinstances) {
> 			System.out.println(a);
> 		}
> 	}
> }
> ...
> Proxy for view class: com.ehtwo.core.util.A of EJB: C2
> Proxy for view class: com.ehtwo.core.util.A of EJB: A1
> Proxy for view class: com.ehtwo.core.util.B of EJB: B1
> {code}
> so, C1 is _not found/injected_ but C2 _is found/injected_, just because C2 re-implements A, which is redundant because it's at the top of the class hierarchy anyway.
> this only happens when "proxy for view" are being applied. (in my case because the EJBs are in a JAR and the Test in a WAR inside an EAR). When running inside one module, and no weld proxies are used, all classes including C1 are injected correctly.
> please move/copy issue to Wildfly-Core or Weld or as you see fit.
