[jira] [Created] (PDFBOX-5561) qpdf shows warnings trying to linearize file modified by PDFBOX

menteith85 created PDFBOX-5561:
----------------------------------

             Summary: qpdf shows warnings trying to linearize file modified by PDFBOX
                 Key: PDFBOX-5561
                 URL: https://issues.apache.org/jira/browse/PDFBOX-5561
             Project: PDFBox
          Issue Type: Bug
    Affects Versions: 2.0.27
            Reporter: menteith85


I have a PDF file* that is generated by a software other than PDFBox. When the PDF is modified by code given below using PDFBOX, *qpdf* shows the following warning:

{{WARNING: modified.pdf: reported number of objects (12991) is not one plus the highest object number (12989) }}
{{qpdf: operation succeeded with warnings; resulting file may have some problems}}

Note the warning is not shown when *qpdf* analyses original (ie. pdf not modified by PDFBox) PDF.

Here's the code to modify PDF in question:

for (final PDPage page: document.getPages()) {
    page.getAnnotations().forEach(annotation - > {
        if (annotation instanceof PDAnnotationLink link) {
            final PDPageXYZDestination destination = new PDPageXYZDestination();
            destination.setPage(document.getPage(1));
            final PDActionGoTo action = new PDActionGoTo();
            action.setDestination(destination);
            link.setAction(action);
        }
    });
}

* I've sent the file to Tilman Hausherr.
