Backport of HV-1055 (https://hibernate.atlassian.net/browse/HV-1055)

Assuming the following
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;
}
The following code returns as expected
assert validator.validate(new B(), Max.class, B.class).size() == 2
But the following fails
// 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
Note that the actual test used group sequence provider but that's not relevant I think.
