Hi,

I don't think that's a spec problem.

The @NotNull constraint should be validated, no matter wether Foo is an interface or an abstract class. Generally constraints on overridden/implemented methods are to be considered, you only may not add any more parameter constraints in subclasses/implementations.

Are you using the Hibernate Validator CDI portable extension? Which container do you use? Could you create an entry with the complete stack trace and a detailed description of your environment to https://forum.hibernate.org/viewforum.php?f=9?

Hi, 

I'm doing some tests with bean validation, and i have some doubts about the behavior of method constraints on inheritance hierarchies.
The specification tells about Liskov substitution, on method constraints within inheritance hierarchies, but i made the test bellow with 
the reference implementation ( hiberante validator 5.1 ), and not understand if this is a bug in implementation or my misunderstanding the specification.

public interface Foo {
     public void doStuff(@NotNull String v);
}

@Named
public class Bar implements Foo {
     public void doStuff(String v) {}
}

Calling bar.doStuff(null), the validation is not fired.
But if i changed Foo interface to an abstract class, and made Bar extends it, the validation is fired and a ConstraintViolationException is propagated.
The test was done with cdi.

What should be the appropriate behavior?
