PDFAuthenticationFailureException

[oscargrgm]

I'm using the PDFViewer library and I have the next System.err:

12-28 17:27:03.866 32545-32545/com.... W/System.err: com.sun.pdfview.decrypt.PDFAuthenticationFailureException: Password failed authentication for both owner and user password

The code is:

@Nullable
    private static Bitmap renderToBitmap(InputStream inputStream) {
        Bitmap bitmap = null;
        try {
            byte[] decode = org.apache.commons.io.IOUtils.toByteArray(inputStream);
            ByteBuffer byteBuffer = ByteBuffer.wrap(decode);
            PDFPage mPdfPage = new PDFFile(byteBuffer, null).getPage(0);
            float width = mPdfPage.getWidth();
            float height = mPdfPage.getHeight();
            RectF clip = null;
            bitmap = mPdfPage.getImage((int) (width), (int) (height), clip, true, true);
        } catch (IOException ex) {
            ex.printStackTrace();
        }
        return bitmap;
    }

and has been found here.

The exact line that the Androir Monitor says the problem is, is the next:
PDFPage mPdfPage = new PDFFile(byteBuffer, null).getPage(0);

Any suggestion? Thank you very much.
