Error generating ticket using Stella Ticket

I'm having trouble generating a ticket for Bradesco bank. I'm using Caelum Stella and IntelliJ IDE, just the basic test code that follows:

public class BradescoBoleto  {


        public static void main(String[] args) {

            Datas datas = Datas.novasDatas()
                    .comDocumento(1, 5, 2016)
                    .comProcessamento(1, 5, 2016)
                    .comVencimento(2, 12, 2016);

            Endereco enderecoBeneficiario = Endereco.novoEndereco()
                    .comLogradouro("Av das Empresas, 555")
                    .comBairro("Bairro Grande")
                    .comCep("01234-555")
                    .comCidade("São Paulo")
                    .comUf("SP");

            //Quem emite o boleto

            Beneficiario beneficiario = Beneficiario.novoBeneficiario()
                    .comNomeBeneficiario("Fulano de Tal")
                    .comAgencia("1824").comDigitoAgencia("4")
                    .comCodigoBeneficiario("76000")
                    .comDigitoCodigoBeneficiario("5")
                    .comNumeroConvenio("1207113")
                    .comCarteira("18")
                    .comEndereco(enderecoBeneficiario)
                    .comDocumento("05.606.206/0001-83")
                    .comNossoNumero("9000206").comDigitoNossoNumero("3");

            Endereco enderecoPagador = Endereco.novoEndereco()
                    .comLogradouro("Av dos testes, 111 apto 333")
                    .comBairro("Bairro Teste")
                    .comCep("01234-111")
                    .comCidade("São Paulo")
                    .comUf("SP");

            //Quem paga o boleto

            Pagador pagador = Pagador.novoPagador()
                    .comNome("Fulano da Silva")
                    .comDocumento("111.222.333-12")
                    .comEndereco(enderecoPagador);

            Banco banco = new Bradesco();

            Boleto boleto = Boleto.novoBoleto()
                    .comBanco(banco)
                    .comDatas(datas)
                    .comBeneficiario(beneficiario)
                    .comPagador(pagador)
                    .comValorBoleto("200.00")
                    .comNumeroDoDocumento("1234")
                    .comInstrucoes("instrucao 1", "instrucao 2", "instrucao 3", "instrucao 4", "instrucao 5")
                    .comLocaisDePagamento("local 1", "local 2");

            GeradorDeBoleto gerador = new GeradorDeBoleto(boleto);


            System.out.println(gerador.toString());
            File pdf = new File("/home/hortela/testeboleto/BancoSemear.pdf");
            gerador.geraPDF(pdf);

        }


}

I'm getting the error:

I've already checked and all libraries and all have been added properly.
