Description

Peter Prusinowski posted on users@ that he got a lot of debug warnings about COSStreams which are not closed. He provided the following code to reproduce the effect:

    public static void generate() throws IOException {
        PDDocument doc = new PDDocument();

        try {
            PDPage page = new PDPage();
            doc.addPage(page);
            PDPageContentStream content = new PDPageContentStream(doc, page);
            BufferedImage bi = ImageIO.read(new File("/tmp/test.png"));
            PDImageXObject img = LosslessFactory.createFromImage(doc, bi);
            content.drawImage(img, 0, 0);
            content.close();
        } finally {
            if (doc != null) {
                doc.save("/tmp/testPdf.pdf");
                doc.close();
            }
        }
    }

    public static void main(String[] args) throws IOException {
        generate();
        generate();
        generate();
    }

I've got the same warnings using that specific code.
