Pessoal estou usando o Vraptor jpa etc. a dúvida é a seguinte tenho um interceptor ele esta funcionando legal, não deixa ir para as outras paginas se nao estiver logado, porem da um erro no console e gostaria de resolver. Toda vez que clico em uma URL para ir para uma outra lógica aparece esse erro.
