Tilman Hausherr updated PDFBOX-4823:
------------------------------------
    Comment: was deleted

(was: I thought we had fixed this problem a few years ago but couldn't find it... so I wrote a quick test:
{code:java}
@Test
public void testDeleteFont() throws IOException
{
    InputStream is = PDFont.class.getResourceAsStream(
            "/org/apache/pdfbox/resources/ttf/LiberationSans-Regular.ttf");
    File tempFontFile = new File(OUT_DIR, "LiberationSans-Regular.ttf");
    OutputStream os = new FileOutputStream(tempFontFile);
    IOUtils.copy(is, os);
    is.close();

    PDDocument doc = new PDDocument();
    PDPage page = new PDPage();
    doc.addPage(page);
    PDPageContentStream cs = new PDPageContentStream(doc, page);
    PDFont font = PDType0Font.load(doc, tempFontFile);
    cs.setFont(font, 50);
    cs.beginText();
    cs.newLineAtOffset(50, 700);
    cs.showText("Test");
    cs.endText();
    cs.close();
    doc.save(new File(OUT_DIR, "testDeleteFont.pdf"));
    doc.close();    Files.delete(tempFontFile.toPath());    
}{code}
It fails in the trunk :()
