> I get this when attempting to flatten the attached file (which is an "improved" version
of the file from the linked issue)
> {{26.08.2019 18:41:00.354 WARN [main] org.apache.pdfbox.pdmodel.interactive.form.PDAcroForm:853
- There has been a widget with a missing page reference. Please report to the PDFBox project}}
>  The intention is to "preserve all non widget annotations". This code reproduces the
problem:
> {code:java}
> PDDocument doc = PDDocument.load(new File("PDFBOX-4636.pdf"));
> List<PDAnnotation> annotations = doc.getPage(0).getAnnotations();
> PDColor red = new PDColor(new float[] { 1, 0, 0 }, PDDeviceRGB.INSTANCE);
> PDColor blue = new PDColor(new float[] { 0, 0, 1 }, PDDeviceRGB.INSTANCE);
> PDAnnotationCircle circleAnnotation = new PDAnnotationCircle();
> circleAnnotation.setContents("Circle Annotation");
> circleAnnotation.setInteriorColor(red);
> circleAnnotation.setColor(blue);
> circleAnnotation.setRectangle(new PDRectangle(100, 700, 100, 50));
> circleAnnotation.setPage(doc.getPage(0));
> circleAnnotation.constructAppearances();
> annotations.add(circleAnnotation);
> doc.save("PDFBOX-4636-annotated.pdf");
> doc.getDocumentCatalog().getAcroForm().flatten();
> doc.save("PDFBOX-4636-flattened-bad.pdf");
> doc.close();
> doc = PDDocument.load(new File("PDFBOX-4636-annotatedAP.pdf")); // PDFBOX-4636-annotated.pdf
opened with Adobe and saved
> doc.getDocumentCatalog().getAcroForm().flatten();
> doc.save("PDFBOX-4636-flattened-good.pdf");
> doc.close();
> {code}
> what should have happened: result file PDFBOX-4636-flattened-good.pdf has 1 annotation.
> what happened instead: result file has PDFBOX-4636-flattened-bad.pdf no annotation, because
the circle annotation has been flattened as well.
