injection of sub-sub-EJB fails with proxy ----------------------------------------- Key: WFLY-7914 URL: https://issues.jboss.org/browse/WFLY-7914 Project: WildFly Issue Type: Bug Components: CDI / Weld, EJB Affects Versions: 10.1.0.Final Environment: WildFly 10.1.0.Final wildfly-arquillian-2.0.2.Final Java(TM) SE Runtime Environment (build 1.8.0_65-b17) Java HotSpot(TM) 64-Bit Server VM (build 25.65-b01, mixed mode) Reporter: Tom Eicher Assignee: Matej Novotny Priority: Major 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.
