[hibernate-issues] [Hibernate-JIRA] Commented: (HV-466) Avoid repeated validation of constraints in certain type hierarchies

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 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}
