Description

With this bean that provides 2 producers that return 2 differents kinds of objects:
@Produces
@Named("list1")
public ArrayList<String> getListe1()

{ return null; }

@Produces
@Named("list2")
public List<Integer> getListe2() { return null; }

And this bean that get injected one of the produced object:
@Inject public List<Integer> listInteger;

The application fails with "javax.enterprise.inject.AmbiguousResolutionException"

Exception in thread "main" javax.enterprise.inject.AmbiguousResolutionException: Ambigious resolution
found beans:
List, Name:list2, WebBeans Type:PRODUCERMETHOD, API Types:[java.lang.Iterable,java.lang.Object,java.util.Collection,java.util.List], Qualifiers:[javax.enterprise.inject.Any,javax.enterprise.inject.Default,javax.inject.Named]
ArrayList, Name:list1, WebBeans Type:PRODUCERMETHOD, API Types:[java.util.AbstractList,java.util.ArrayList,java.util.RandomAccess,java.lang.Iterable,java.util.AbstractCollection,java.util.Collection,java.lang.Object,java.io.Serializable,java.util.List,java.util.Collection,java.lang.Iterable,java.util.List,java.lang.Cloneable], Qualifiers:[javax.enterprise.inject.Any,javax.enterprise.inject.Default,javax.inject.Named]

If we change the return type of the firts producer from ArrayList by List, it works !!
