ClassUtils.setValue tries to set null on primitive fields

[ctrueden]

When calling ClassUtils#setValue(field, object, value) with a null value, on a primitive type field, the method ultimately tries to assign the null value to the field, which bombs out with:

java.lang.IllegalArgumentException: Can not set long field foo.bar.myField to null value

This may actually be a problem with the ConversionUtils#convert(Object, Type) method. If the Type is a primitive and the Object is null, it should not return null.
