Why doesn't the jasper report throw a JRFontNotFoundException if there is no font for the PDF?

Question

I read

• stack overflow
• stack overflow
• http://community.jaspersoft.com/questions/543275/fonts-problem-while-using-jasper-reports-402-version
• http://refermycode.com/remove-font-dependency-in-jasper-report/

and I expected Jasper Reports to output JRFontNotFoundExceptionif the font is not installed on the computer.

But my application does not quit JRFontNotFoundException, although I did not install the used font "Helvetica" on any (Jaspersoft Studios, JasperReports, Adobe Acrobat Reader).

JRXML:

Java:

private byte[] createPdf() {

    try {
        InputStream is = getClass().getResourceAsStream("MyReport.jasper");
        JasperReport jasperReport = (JasperReport) JRLoader.loadObject(is);
        Map<String, Object> parameters = new HashMap<String, Object>();
        parameters.put("timestamp", new Date());
        JRDataSource jrDataSource = new JRBeanCollectionDataSource(new Vector(), false);
        JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, jrDataSource);
        byte[] pdf = JasperExportManager.exportReportToPdf(jasperPrint);
        return pdf;
    } catch (JRException e) {
        throw new RuntimeException("Could not create PDF.", e);
    }
}

The reason is that it JRFontNotFoundExceptionis called only if the font in the attribute is fontNamenot set:

, , , fontName , JasperReports , , Java.

PDF, pdfFontName ( )?

pdfFontName , , , itext, jasper-reports JRFontNotFoundException, , itext , JRRuntimeException.
