Bom dia Romário, vou enviar as classes novas que foram implementadas nos exercícios das aulas 8 e 9, pois até em tão estava tudo funcionando bem.

package br.com.caelum.vraptor.interceptor;

import javax.inject.Inject;

import br.com.caelum.vraptor.AroundCall;

@Intercepts
public class AutorizadorInterceptor {

    private final UsuarioLogado usuarioLogado;
    private final Result result;
    private final ControllerMethod controllerMethod;


     @Inject
        public AutorizadorInterceptor(Result result, 
                UsuarioLogado usuarioLogado, ControllerMethod controllerMethod) {
            this.result = result;
            this.usuarioLogado = usuarioLogado;
            this.controllerMethod = controllerMethod;
        }

    @Accepts
     public boolean accepts(){
        return !controllerMethod.containsAnnotation(Public.class);
    }

    @AroundCall
    public void intercepta(SimpleInterceptorStack stack){

        if(usuarioLogado.getUsuario()==null){
            result.redirectTo(LoginController.class).formulario();

Lincoln, não fui eu que marquei como resolvido, mas não se preocupe, que irei olhar seu código e te ajudar, porém se quiser abrir um novo tópico tudo bem.

Lincoln, em sua classe AutorizadorInterceptor faltou implementar o Construtor:

 public AutorizadorInterceptor() {
    super(null, null, null)
    }
por Lincoln John Campos Ribeiro

Romário, quando coloco o construtor dá o seguinte erro: The constructor Object(null, null, null) is undefined

solução!

Romário, resolvi o problema. Na internet havia algumas recomendação para não utilizar a notação @NotEmpty, retirei da classe Produto e não deu mais erro.
