As we discussed before, this exception will be thrown if the column
type doesn't match the generic type. Because of type erasure I don't
know of any way to validate the types.
Sebb, are you advocating putting an @throws ClassCastException in the
Javadocs stating that if the column type doesn't match the generic
type, then this exception will be thrown? What would others like to
see for documentation here?
Thanks!
