[jboss-jira] [JBoss JIRA] (WFLY-3632) @Inject broken for parameterized interfaces

[Alexander Langer (JIRA)]

     [ https://issues.jboss.org/browse/WFLY-3632?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alexander Langer updated WFLY-3632:
-----------------------------------

    Description: 
@Inject is broken on Wildfly 8.1.0 Final when the interface to be injected is parameterized with a type that extends another type.  Example code:

{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());
    }
}
{code}

output:
{code}
22:30:25,904 INFO  [stdout] (ServerService Thread Pool -- 50) ##### foo is unsatisfied = true
22:30:25,905 INFO  [stdout] (ServerService Thread Pool -- 50) ##### bar is unsatisfied = false
{code}

The same code works on JBoss AS 7.1.1, so something must have changed for Wildfly.  

The attached small example project can be used to reproduce the error.
