      Description

      As explained in my comment in the forum thread, some PDF files make icepdf enter an infinite loop when looking for the content of an inline image.

      {code}
      stackTrace:

      {code}

      I reproduced this with the 2 PDF files from the forum link and some test code that does

      {code}
      Document document = new Document();
      document.setByteArray(pdf, 0, pdf.length, null);

      if (document.getNumberOfPages() <= 0) {
              throw new IllegalArgumentException("No page!");
      }

      BufferedImage image = (BufferedImage) document.getPageImage(0,
                          GraphicsRenderingHints.SCREEN, Page.BOUNDARY_CROPBOX, 0f, 1.0f);
      ImageIO.write(image, "jpg", baos);
      return baos.toByteArray();
      {code}
