Review abstract class type for AttributeAccessorSupport

[mjd507]

Hello team,

I just start reading the source of bean part, when I look at the class AttributeAccessorSupport, it's showing as an abstract class, but actually, it implements all the methods from its interface AttributeAccessor, also in the unit test part, I see we give a simple extension class which implement nothing.

is it intended to be a abstract from a design perspective ?

similarly for BeanUtils, seems to be intentional

This is intentional as far as those are not meant to be used as concrete classes. AttributeAccessor specifically is not meant to be the sole interface a particular class implements, it's rather a side characteristic.
