/**
 * A <b>sscce</b> (Short, Self Contained, Correct Example) showing that the
 * simple custom Email validation constraint taken from <a href="http://blog.jteam.nl/2009/08/04/bean-validation-integrating-jsr-303-with-spring/"
 * >this blog</a> gives a validation result that is not Serializable with
 * Hibernate Validator 4.0.2.GA with underlying cause that
 * <p/>
 * <code>org.hibernate.validator.internal.util.annotationfactory.AnnotationProxy</code>
 * <p/>
 * <p/>
 * Note that Hibernate Validator does not guarantee at all that a
 * {@link ConstraintViolation} is Serializable because an entity need not be
 * Serializable, but otherwise there should not be much of a problem (right?).
