I'm looking at examples from https://github.com/pmuir/jboss-as-developer-guide/tree/master/quickstarts
There is org.jboss.as.quickstarts.login.EJBUserManager:
And there is also another bean org.jboss.as.quickstarts.login.ManagedBeanUserManager:
This code works in Weld even if EJBUserManager.getUsers() is not annotated @Alternative. But regarding the spec such a method has an ambiguous EL name "users":
5.3.1. Ambiguous EL names
An ambiguous EL name exists in an EL expression when an EL name resolves to multiple beans. When an ambiguous EL
name exists, the container attempts to resolve the ambiguity. If any of the beans are alternatives, the container eliminates
all beans that are not alternatives, except for producer methods and fields of beans that are alternatives. If there is exactly
one bean remaining, the container will select this bean, and the ambiguous EL name is called resolvable.
There is a comment from Pete Muir:
This looks to me like a bug in Weld (one that crept in from a pre-final spec revision) - that it checks if the declaring bean class is an alternative, and if it is, makes the producer an alternative. Can you file a WELD issue for this? I'll update the quickstart to explicitly make the producer an alternative.
