      create own array of property descriptors to:

            - prevent memory leaks by Introspector's cache
            - get correct type for generic properties from superclass
               that are limited to a specific type in beanClass
              see http://bugs.sun.com/view_bug.do?bug_id=6528714
             we cannot use BeanUtils.getPropertyDescriptors because of issue SPR-6063

      Parameters:
        `refClass` - calling class for class loading.
        `beanInfo` - Bean in question
        `beanClass` - class for bean in question
        `propertyDescriptors` - raw descriptors

    - #### getAnnotationForMethodOrContainingClass

          public static <T extends Annotation> T getAnnotationForMethodOrContainingClass(Method m,
                                                                         Class<T> annotationType)

      Look for a specified annotation on a method. If there, return it. If not, search it's containing class. Assume that the annotation is marked @Inherited.
      Parameters:
        `m` - method to examine
        `annotationType` - the annotation type to look for.
