[jira] [Updated] (PDFBOX-5559) QPDF prints warnings about a PDF modified by PDFBOX

menteith85 updated PDFBOX-5559:
-------------------------------
Description:
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}
