Tilman Hausherr commented on PDFBOX-5559:
-----------------------------------------

You didn't attach the modified PDF and I'm too lazy to run it, but the original PDF has the same "problem":
 !screenshot-1.png! 
You created the same page twice.
Please create another issue for the other file (file.pdf), but only if it was created by PDFBox.

> Hi!
> I created a sample PDF file with PDAnnotationLink using PDFBox. Then I changed action from PDActionURI to PDActionGoTo. The modified pdf is correctly working in Okular (a pdf viewer for Linux) but *qpdf* (version 11.2.0) emits the following warning:
> {code:java}
> ❯ qpdf --linearize --replace-input sample_modified.pdf 
> WARNING: sample_modified.pdf, object 2 0 at offset 88: kid 1 (from 0) appears more than once in the pages tree; creating a new page object as a copy 
> qpdf: there are warnings; original file kept in sample_modified.pdf.~qpdf-orig 
> qpdf: operation succeeded with warnings; resulting file may have some problems{code}
> Please find below the code I used to modify pdf. I can also provide code to create that pdf if needed.
> {code:java}
> final PDPage page = doc.getPage(0);
> final PDPageXYZDestination destination = new PDPageXYZDestination();
> destination.setPage(page);
> final PDActionGoTo action = new PDActionGoTo();
> action.setDestination(destination);
> final PDAnnotationLink annotationLink = new PDAnnotationLink();
> annotationLink.setAction(action);
> float X_MARGIN_LEFT = 50F;
> float BOX_WIDTH = 240F;
> float TEXT_LINE_HEIGHT = 14F;
> final PDRectangle position = new PDRectangle();
> final int x = 120;
> final int y = 120;
> position.setLowerLeftX(x);
> position.setLowerLeftY(y);
> position.setUpperRightX(X_MARGIN_LEFT + BOX_WIDTH);
> position.setUpperRightY(y + TEXT_LINE_HEIGHT);
> annotationLink.setRectangle(position);
> page.setAnnotations(List.of(annotationLink));
> doc.save("sample_modified.pdf");{code}
>  
> *qpdf* complains also about a different pdf (copyrighted) modified in similar way. The warning reads:
> {code:java}
> WARNING: file.pdf: reported number of objects (12991) is not one plus the highest object number (12989){code}
