 * once per project if possible - see the usage info in the {@link ReflectionBasedJsr303AnnotationTrollerBase}
 * class-level javadocs.
 * <p>The given set of extra packages for constraint annotation searching will be passed into {@link
 * #getFinalPackagesToSearchForConstraintAnnotations(Set)} to generate the final set of packages that are searched.
 * If you don't want the {@link #DEFAULT_CONSTRAINT_SEARCH_PACKAGES} default packages to be searched you can
 * override {@link #getDefaultPackagesToSearchForConstraintAnnotations()}.

     * that extensions of this class will care about.
