I found this in the spec: Hi Martin, I found this: In 4.3 Specialization, @Alternative @Specializes public class MockAsynchronousService extends AsynchronousService { ... } *When an enabled bean*, as defined in Section 5.1.2, “Enabled and disabled beans”, specializes a second bean, we can be certain that the second bean is never instantiated or called by the container. If the alternative bean is not enabled, it should not specialise/disable another bean. Do you agree with me or you still want me to raise a question in cdi-dev?
