[Resolvido] VRaptor+JasperReport {de novo}

Bom dia pessoal, titulo estranho né, falo de novo pois há N Tópicos com esse titulo, e é algo que se torna muito complicado de fazer os famosos relatórios.

Então, já usei o jasperMaker do nosso amigo lavieri e antes me dava um resultado satisfatorio, agora de qualquer forma que eu faça me retorna um nullPointer no fillReport

já debuguei de N maneiras e nenhuma resposta, dai fiz da forma padrão mesmo e aconteceu a mesma coisa.
Já vi se está alimentando a lista, já vi se está convertendo para collection e tudo isso faz mas na hora de fazer o fillReport me retorna nullPointer

Olha como estou fazendo

public void geraRelatorio()
			throws Exception {

		/*
		 * Codigo para consultar a lista
		 */
		List<Produto> list = dao.listaTudo();

		/*
		 * Final da consulta, retorna array para converter em pdf
		 */

		// Localiza o contexto da pasta onde esta localizado o .jasper
		String pathJasper = context.getRealPath("/WEB-INF/jasper") + "/";

		// Faz o mapeamento do context para levar o .jasper a conversao em bytes
		Map<String, String> parametros = new HashMap<String, String>();
		parametros.put("SUBREPORT_DIR", pathJasper);

		try {
			// Recebe a lista do array populado
			JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(list);
			// pega o ds + a conexao para ir ate o ireport para listar o array
			// dentro do relatorio
			JasperPrint impressao = JasperFillManager.fillReport(pathJasper
					+ "/relProduto.jasper", parametros, ds);

			// converte o relatorio em bytes gerando o pdf
			byte[] bytes = JasperExportManager.exportReportToPdf(impressao);
			byte[] arquivo = bytes;

			// Tratamento para exportacao do pdf para a url do browser e o
			// tratamento de erros.
			String nomeDoArquivo = "relProduto.pdf";
			response.setContentType("application/x-msdownload");
			response.setHeader("Content-Disposition", "attachment; filename=".concat(nomeDoArquivo));
			response.setContentLength(arquivo.length);
			ServletOutputStream sos = response.getOutputStream();
			sos.write(arquivo, 0, arquivo.length);
			sos.flush();
			sos.close();
		} catch (Exception e) {
			e.printStackTrace();
		}

Mudando um pouco o log;
