Nested ParameterizedTypes throws a ClassCastException #118

When a property has nested ParameterizedType instances, a ClassCastException is thrown:

java.lang.ClassCastException: sun.reflect.generics.reflectiveObjects.ParameterizedTypeImpl cannot be cast to java.lang.Class

This happens for example with this construction:

public List<List<String>> names;

The reason for this happening is that the single generic in the list of generics in the ParameterizedType contains another ParameterizedType. This instance cannot be cast to a class, but must have its rawType extracted to see its Class.

#118 Nested ParameterizedTypes throws a ClassCastException
9e44760 
When a type is a nested generic (eg, List<List<String>>) it threw a
ClassCastException, even if no mapping took place. Fixed by checking
the Type in ```AbstractBeanPropertyClass``` and calling for rawType
if it concerns a ParameterizedType.
