> Peter Pusinowski 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:
> {code}
>     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();
>     }
> {code}
> I've got the same warnings using that specific code.
