Hibernate Validator: default group sequence does not honor group hierarchy

public interface Min {}

public interface Max extends Min {}

@GroupSequence({Max.class, A.class})
public class A {
    @NotNull(groups=Max.class)
    public String foo;

    @NotNull(groups=Min.class)
    public String bar;
}

public class B {
    @NotNull(groups=Max.class)
    public String foo;

    @NotNull(groups=Min.class)
    public String bar;
}

assert validator.validate(new B(), Max.class, A.class).size() == 2

// bar is ignored as Min is not considered when Max is evaluated for default sequence
// so size == 1
assert validator.validate(new A(), Max.class, A.class).size() == 2
