  - ### getPropertyDescriptorsAvoidSunBug

    public static PropertyDescriptor[] getPropertyDescriptorsAvoidSunBug(Class<?> refClass, BeanInfo beanInfo, Class<?> beanClass, PropertyDescriptor[] propertyDescriptors)
    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.
