            File pdfFile = new File("lorem_1.pdf");

            System.out.println("Load pdf into PDDocument: " + pdfFile);
            doc = PDDocument.load(pdfFile);
            System.out.println("Loaded pdf\n");

            File xfdfFile = new File("lorem.xfdf");
            System.out.println("\tLoad xfdf into FDFDocument: " + xfdfFile);
            fdf = FDFDocument.loadXFDF(xfdfFile);

            // Lookup with annotations exists
            List<FDFAnnotation> fdfAnnots = fdf.getCatalog().getFDF().getAnnotations();
            // add each annotation in the xfdf into the document
            for (FDFAnnotation fdfAnnot : fdfAnnots)
            {
                PDPage page = doc.getPage(fdfAnnot.getPage());
                List<PDAnnotation> pageAnnots = page.getAnnotations();
                annot = PDAnnotation.createAnnotation(fdfAnnot.getCOSObject());
                annot.setLocked(true);
                pageAnnots.add(annot);
            }
            System.out.println("\tAdded into PDF");
            fdf.close();

            doc.save("lorem_stamp_markup.pdf");

My first impression: The shading dictionary in the annotation is incomplete. The code in FDFAnnotationStamp.parseDictElement() is incomplete, possibly also the code in parseArrayElement.
