This is a solution

public TO getTo() throws Exception {
    if(to == null) {
        try {
            to = ((Class) ((ParameterizedType) this.getClass().getGenericSuperclass())
                    .getActualTypeArguments()[0]).newInstance();
        } catch(ClassCastException cce) {
            cce.printStackTrace();
            to = ((Class) ((ParameterizedType) (((Class) this.getClass()
                    .getAnnotatedSuperclass().getType()).getGenericSuperclass()))
                            .getActualTypeArguments()[0]).newInstance();
        }
    }
    return to;
}
