    We have a case where we create a PDF file and than append a few more to it (created not by PD4ML library, but somewhere else).
    We noticed an issue with a specific PDF file that throw an error when we try to append it (while it works for all other pdf).

    We are limited to Java8 and we use PD4ML v4.0.15 (and I just upgraded to 4.0.18, same issue)

    Here is how I merge pdf

    private void merge(File file, PdfDocument pdfAppend) throws NotesException, InvokeException, IOException {
    InputStream fis = new FileInputStream(file);
    PdfDocument pdf = new PdfDocument(fis, null);

    pdf.append(pdfAppend); // error happens here, line 198
    OutputStream fos = new FileOutputStream(file);


    file is a PDF file I created using PD4ML library
    pdfAppend is an external pdf file

    Here is error trace

    I confirm we do not set any password.

    Any idea would be very much welcome!
