 If there is exactly one bean remaining, the container will select this bean, and the ambiguous dependency is called resolvable.
 
+For the purpose of determining the priority of any producer method or field during ambiguity resolution, the priority of the producer method or field is considered first.
+If the producer method or field does not have a priority, the priority of the managed bean that declares the producer method or field is used.

 The container must validate all injection points of all enabled beans, all observer methods and all disposer methods when the application is initialized to ensure that there are no unsatisfied or unresolvable ambiguous dependencies.
 If an unsatisfied or unresolvable ambiguous dependency exists, the container automatically detects the problem and treats it as a deployment problem.
