> how to get those classes
case a) JAXB 
case b) a class persisted to Hibernate where the state of null is also valid and needs to
be reacted upon accordingly

> NPE
why would i get one of those when just copying the property ?
because of converters?
afer all i expect smth. like this to be performed: a.isBooleanClass(  b.isBooleanClass() )


> Java doc
i had read that somewhere along trying to find the problem but it didnt click that this meant
"native boolean". 
u see, with autoboxing I dont care anymore or only a little about native or not...

> it seems that an isXXX() style property returning an java.lang.Boolean Object is NOT
recognized as the getter peoperty -- at least it wont copy it.
> Hence, the test case below will fail.
> I suggest to handle these props as well, as for a user of BeanUtils this was/is quite
surprising to me -- and probably others.
