Problemas com content-lenght do Weblogic

Front-end
#1

Pessoal, estou com um problema no weblogic…
Tenho um código que gera um relatório e o disponibiliza para o download na web…

No entanto, ao gerar o relatório acontece a seguinte exception:

java.net.ProtocolException: Exceeded stated content-length of: '1991' bytes
        at weblogic.servlet.internal.ServletOutputStreamImpl.checkCL(ServletOutputStreamImpl.java:219)
        at weblogic.servlet.internal.ServletOutputStreamImpl.write(ServletOutputStreamImpl.java:166)
        at com.telefonica.sirs.update.reports.ReportsBuilder.exportPDFReport(ReportsBuilder.java:134)
        at com.telefonica.sirs.update.reports.ReportsBuilder.executeReporteMigracionDatos(ReportsBuilder.java:98)
        at com.telefonica.sirs.update.reports.MigrationReport.buildAndExecuteReport(MigrationReport.java:67)
        Truncated. see log file for complete stacktrace

Estou usando o seguinte código para gerar o relatório

static void executeReporteMigracionDatos(ReportNames jasper, String centralName,
			String userProcess, String dateProcess, List<? extends Object> reportFields, 
			ServletContext context, HttpServletResponse response) 
			throws IOException, JRException, IllegalArgumentException {
		
		Map<String, Object> parameters = new HashMap<String, Object>();		
		parameters.put("centralName", centralName);
		parameters.put("dateProcess", dateProcess);
		parameters.put("userProcess", userProcess);
		
		File reportFile = new File(context.getRealPath("path dos arquivos .jasper" 
				+ jasper.name().concat(".jasper")));	
		
		System.out.println("Arquivo para o relatório " + reportFile.getName());
		InputStream reportStream = new FileInputStream(reportFile);
		
		JRDataSource beanReport = new JRBeanCollectionDataSource(reportFields);
		JasperPrint print = JasperFillManager.fillReport(reportStream, parameters, beanReport);
		
		System.out.println("Jasper Print " + print.getName());
		
		// Verificando o tipo do relatório que será gerado
		switch (jasper) {
			case Reporte_Migracion_PDF:
				exportPDFReport(print, reportFile, response);
				break;			
			case Reporte_Migracion_XLS:
				exportXLSReport(print, reportFile, response);
				break;
			case Reporte_Eventos_Rechazos_SNU_PDF:
				exportPDFReport(print, reportFile, response);
				break;
			case Reporte_Eventos_Rechazos_SNU_XLS:
				exportXLSReport(print, reportFile, response);
				break;			
			case Reporte_Eventos_Rechazos_LEN_PDF:
				exportPDFReport(print, reportFile, response);
				break;
			case Reporte_Eventos_Rechazos_LEN_XLS:
				exportXLSReport(print, reportFile, response);
				break;
			case Reporte_Eventos_Rechazos_CSS_PDF:
				exportPDFReport(print, reportFile, response);
				break;
			case Reporte_Eventos_Rechazos_CSS_XLS:
				exportXLSReport(print, reportFile, response);
				break;
			default : 
				throw new IllegalArgumentException("The parameter[jasper] = " + jasper.name() + 
						" is not a valid type of supported reports");				
		}
		
	}


private static void exportPDFReport(JasperPrint print, File reportFile,
			HttpServletResponse response) throws JRException, IOException {
		
		byte[] pdfBytes = JasperExportManager.exportReportToPdf(print);
		
		if (pdfBytes != null && pdfBytes.length > 0) {
			response.setContentType("application/pdf");
			
			String fileName = reportFile.getName().replace("_PDF", "").replace(".jasper", "").trim();
			response.setHeader("Content-Disposition", "attachment;filename="+fileName+".pdf");
			response.setContentLength(pdfBytes.length);
			
			ServletOutputStream outputStream = response.getOutputStream();
			outputStream.write(pdfBytes, 0, pdfBytes.length);
			
			JasperExportManager.exportReportToPdfStream(print, outputStream);
		}
	}

Alguém tem alguma idéia do motivo deste erro?
Grato desde já
