             Summary: NPE if RAFDataStream.getCurrentPosition() when TrueTypeFont created from file is reused
                 Key: PDFBOX-3826
                 URL: https://issues.apache.org/jira/browse/PDFBOX-3826
             Project: PDFBox
          Issue Type: Bug
          Components: FontBox
    Affects Versions: 2.0.6
            Reporter: Tilman Hausherr

    @Test
    public void testMultipleFontFileReuse() throws IOException, URISyntaxException
    {
        URL url = PDFontTest.class.getClassLoader().getResource(
                "org/apache/pdfbox/ttf/LiberationSans-Regular.ttf");
        File file = new File(url.toURI());

        TrueTypeFont ttf = new TTFParser().parse(file);

        for (int i = 0; i < 32; ++i)
        {
            try (PDDocument doc = new PDDocument())
            {
                PDPage page = new PDPage();
                doc.addPage(page);
                PDFont font = PDType0Font.load(doc, ttf, true);
                try (PDPageContentStream cs = new PDPageContentStream(doc, page))
                {
                    cs.beginText();
                    cs.setFont(font, 10);
                    cs.showText("testMultipleFontFileReuse");
                    cs.endText();
                }
                doc.save(new ByteArrayOutputStream());
            }
        }
    }
{code}
This happens only if the TrueTypeFont is created from a file, not when it is created from a stream (PDFBOX-3337). It worked in 2.0.0 but no longer since 2.0.1.
