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 java.lang.annotation.Annotation> T getAnnotationForMethodOrContainingClass(java.lang.reflect.Method m,
                                                                                                    java.lang.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.
