setAccessible

public static <T extends AccessibleObject> T setAccessible(T o)

setAccessible

public static <T extends AccessibleObject> T setAccessible(T o,
                                                           boolean b)

                                       throws IOException
Throws:
IOException

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
Returns:

findMethod

public static Method findMethod(Class<?> cls,
                                String name,
                                Class<?>... params)
Try to find a method we can use. If the object implements a public interface that has the public version of that method, we'll use the interface defined method in case the actual instance class is not public
