Hardy Ferentschik updated HV-466:
---------------------------------
Affects Version/s: 4.1.0.CR1
> Avoid repeated validation of constraints in certain type hierarchies
> --------------------------------------------------------------------
>
> Key: HV-466
> URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-466
> Project: Hibernate Validator
> Issue Type: Bug
> Components: engine
> Affects Versions: 4.1.0.CR1
> Reporter: Gunnar Morling
> Priority: Minor
> Fix For: 4.x
>
>
> Let there be the following type hierarchy where the same interface is implemented by two types in an inheritance hierarchy:
> {code:java}
> public interface A {
>
> @NotNull
> String getA();
> }
>
> public class B implements A {
> public String getA() {
> return null;
> }
> }
> public class C extends B implements A {
>
> }
> {code}
> When validating an instance of {{C}} the {{@NotNull}} constraint on {{A#getA()}} is evaluated twice when traversing the type hierarchy of {{C}} in {{ValidatorImpl}}.
> This seems to be against the BV spec. which says in chapter 3.5:
> {quote}
> Note that this [algorithm] implies that a given validation constraint will not be processed more than once per validation.
> {quote}
