Description

EI recently tested upgrading the PDFBox version in my project from 1.8.8 to 2.0.0-SNAPSHOT

I ran into problems when printing silently via PDFPrinter.java

I ran this code:

private Status doPdfPrint(Document document, PrintService printService) {
        ByteArrayInputStream bais = null;
        PDDocument doc = null;
        PrinterJob printerJob = PrinterJob.getPrinterJob();

        try {
            printerJob.setPrintService(printService);
            bais = new ByteArrayInputStream(document.getDecodedData());

            doc = PDDocument.load(bais, true); //Force load

            PDFPrinter pdfPrinter = new PDFPrinter(doc);
            pdfPrinter.silentPrint(printerJob);

            //doc.silentPrint(printerJob);

            doc.close();
            bais.close();
        } catch (IOException | PrinterException e) {
            log.warn("Failed to print! Exception occurred: {}", e.getMessage());
            log.debug("EXCEPTION", e);
            return Status.PRINTING_FAILED;
        } finally {
            IOUtils.closeQuietly(bais);
            IOUtils.closeQuietly(doc);
        }
        return Status.PRINTING_OK;
    }

Which resulted in the following stacktrace:
