Na verdade o meu relatorio é só um select geral:
select * from alunos
Nada mais por isso o relatório não é necessário parametros.
montei outro relatório e o erro é o mesmo:

tenta usar esse código pra gerar o relatório:
jasperReport = JasperCompileManager.compileReport(caminhoDoRelatorio); jasperPrint = JasperFillManager.fillReport(jasperReport, new HashMap(), conn.getConexao()); byte[] oRelatorio = JasperExportManager.exportReportToPdf(jasperPrint); ///Faz conversao byte[] para InputStream InputStream arquivo = new ByteArrayInputStream(oRelatorio); return new InputStreamDownload(arquivo, "application/pdf", "relatorio.pdf");

Lucas,
Boa Tarde!
Mais uma vez fomos fechando os caminhos pra solução.
Pensei o seguinte em pegar versão mais recente do itext, jasper e common digest.
E era isso acredita resolveu o problema, menos mal.
Abraço.
e valeu pela atenção e ajuda.
