[Alexander Langer (JIRA)]

Title: Message Title

Alexander Langer created an issue   Weld / WELD-1723 Injection of parameterized types does not longer work in 2.x (starting with 2.0.0.Alpha3) Issue Type: Bug Affects Versions: 2.2.4.Final, 2.0.0.Alpha3 Assignee: Unassigned Created: 26/Aug/14 6:20 AM Priority: Major Reporter: Alexander Langer Security Level: Public (Everyone can see) Injection of parameterized types does not work correctly in 2.0.0.Alpha3 and up, if the parameterized type "extends" another type. It used to work in 1.x and up to 2.0.0.Alpha2. Example code: public interface Foo<T extends Serializable> { } // will fail public class FooBean implements Foo { } public interface Bar<T> { } // will work public class BarBean implements Bar { } @Singleton @Startup public class TestSingleton { @Inject private Instance<Foo> foo; @Inject private Instance<Bar> bar; @PostConstruct public void init() { System.out.println("##### foo is unsatisfied = " + foo.isUnsatisfied()); for (Foo f : foo) System.out.println("foo is: " + f.getClass().getCanonicalName()); System.out.println("##### bar is unsatisfied = " + bar.isUnsatisfied()); for (Bar b : bar) System.out.println("bar is: " + b.getClass().getCanonicalName()); } } ================================== WORKS in Weld 1.x and 2.0.0.Alpha2: (this is the expected output) ================================== 16 [org.example.weldtest.App.main()] INFO org.jboss.weld.Version - WELD-000900 2.0.0 (Alpha2) 50 [org.example.weldtest.App.main()] INFO org.jboss.weld.Bootstrap - WELD-000101 Transactional services not available.
