Per default, BeanUtils only supports classes complying to the Java Beans
specification. This is obviously not the case for your class.

From version 1.9.x onwards, BeanUtils allows extending the introspection
facilities so that non-conform properties could be detected, too. This
is described in the user guide [1].

I am not sure whether this is an option for you because it requires some
effort to implement a custom BeanIntrospector just to add support for
these properties with incompatible argument types. But AFAIK, this is
the only way to make BeanUtils recognize them.
