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