Bom dia!
Eu fiz um cadastro de "um" usuário na tabela para não gerar esse erro a primeira vez que ele ocorreu...
Porém eu fiz um teste digitando um usuário correto, porém com uma senha "errada", e o sistema ao invés de chamar a msg de erro gerou o erro acima...

note The full stack trace of the root cause is available in the Apache Tomcat/8.5.8 logs.
Apache Tomcat/8.5.8Meu método no UsuárioDao:
public Usuario busca(String login, String senha) {
TypedQuery<Usuario> query = manager
.createQuery("select u from Usuario u where u.login = :login and u.senha = :senha", Usuario.class);
query.setParameter("login", login);
query.setParameter("senha", senha);
return query.getSingleResult();
}Adicionei a anotação @Valid no método autentica do LoginController, mas msms assim não chamou a msg de erro...
@Open
public void autentica(@Valid String login, String senha) {
Usuario usuario = usuarioDao.busca(login, senha);
if (usuario != null) {
usuarioLogado.fazLogin(usuario);
result.redirectTo(UsuarioController.class).lista();
} else {
validator.add(new SimpleMessage("login_invalido", "Usuário ou senha incorretos!"));
validator.onErrorRedirectTo(this).formularioLogin();
}
}
