------- Additional Comments From niallp@apache.org  2005-02-09 12:44 -------
The reason for the problem lies in the fact that the anonymous class is private.

The BeanUtils's describe method does the following...

   if (descriptors[i].getReadMethod() != null) {
       desription.put(name, getProperty(bean, name);
   }

.. getProperty() is calling getNestedProperty()
.. getNestedProperty() is calling PropertyUtil's getNestedProperty()
.. getNestedProperty() is calling getSimpleProperty()
.. getSimpleProperty() is calling getReadMethod()
.. getReadMethod() is calling MethodUtil's getAccessibleMethod()

MethodUtil's getAccessibleMethod() method checks that the declaring class of 
the method is public, otherwise it returns null rather than the method.

Since it is a private class, if BeanUtils did try to invoke the method it would 
fail. So it looks to me like we need to change the BeanUtils.describe() method 
to check that the bean is a public class and throw an exception if it isnt.

The answer for you though is that you can't use BeanUtils with private classes.
