Running attached application gives the error:

WELD-001409 Ambiguous dependencies for type [Interface1<UUID, String>] with qualifiers [@Default] at injection point [[field] @Inject private test.Bean.dependency]. Possible dependencies [[Managed Bean [class test.ConcreteClass1] with qualifiers [@Any @Default], Managed Bean [class test.ConcreteClass2] with qualifiers [@Any @Default], Managed Bean [class test.ConcreteClass3] with qualifiers [@Any @Default]]]

But only ConcreteClass3 has required type of Interface1<UUID, String>

When ConcreteClass1 and ConcreteClass2 extens AbstractClass1 instead of AbstractClass2 everything works as expected.
