title: how to execute validation on property annotated with @valid before a class level annotation?
body: <p>Assume a class A associates class B, I need data validation between A and B, so I add a custom annotation on class A class level, also make it in a different group, so I can control the execution order, but it seems only work on A, I want the custom validation be executed after the basic validation done both on A and B, but it seems doesn't, the validation on B is executed after, how can make it before the custom validation?
  Here are the sample codes:</p>
  
  <pre><code>@XXXValidation(groups = Second.class)
  @GroupSequence({A.class, Second.class})
  public class A {
     @valid
     private B b;
  }
  public class B {
     @NotNull
     private String name;
  }
  </code></pre>
