Two session beans:

• same name
• implementing the same local interface (Animal) and declaring no other views
• deployed in two different modules, one module (A) is visible to the other (B).

When trying to inject Animal in the module B, once I get an instance of the first bean, next time an instance of the second one. The correct behavior would be DeploymentException due to ambiguous dependency.

interface Animal {}

@Stateful(name = "Animal")
public class Cat implements Animal {}

@Stateful(name = "Animal")
public class Dog implements Animal {}

public class Bar {
    @Inject
    private Animal animal;
}

Deployment structure:
EAR

• ejb.jar: Animal, Dog
• test.war: Bar, Cat
