WildFly not triggering method validation automatically

[oscarfh]

I have the following structure in my project:

public interface MyInterface {
    public String lookup(@NotNull String text);
}

@Stateless
public class MyBean implements MyInterface {
     public String lookup(String text){
          return "found";
     }
}

public class Presenter{
    @EJB
    private MyBean myBean;

    public void lookup(final String term) {
         myBean.lookup(term);
    }
}

I was expecting Wildfly to call the method validation when I call lookup, causing an exception to be thrown when term is null.

It is not happening and I have to explicitly anotate my bean with an intereceptor that performs the validation.

Reading Hibernate Validator's documentation, it states that the validation will be automatically performed.

What should I do to so WildFly performs the validation? Am I missing something?

I dont't think it is important, but the lookup method in the Presenter is called using an observer design pattern.
