Juste un coup d'oeil à la méthode suivante de PdfWriter:

http://api.itextpdf.com/itext/com/itextpdf/text/pdf/PdfWriter.html#setPageEmpty(booléen)

Devrait fonctionner de la sorte:

Document doc = new Document();
PdfWriter pdfWriter
        = PdfWriter.getInstance(document, new FileOutputStream("file.pdf"));
pdfWriter.setPageEmpty(false);
doc.newPage();
doc.close();

Vous dire à l'auteur que la page n'est pas vide, même si elle est, donc, une nouvelle page sera créée.
