> 1/ I sign a file using this method
> 	public static void signByPdfbox(
> 			File inputPDF,
> 			File outputPDF,
> 			KeyStore ks,
> 			String password) 
> 	throws IOException, UnrecoverableKeyException, KeyStoreException, NoSuchAlgorithmException, COSVisitorException, SignatureException {
> 		PDDocument inputDoc = PDDocument.load(inputPDF);
> 		
> 		
> 		PADESSigner signer = new PADESSigner(ks, password);
> 		
> 		signer.setSignatureName("Hello1");
> 		signer.setSignatureReason("Why noy");
> 		signer.setSignatureLocation("Curacao");
> 		signer.setSignatureContactInfo("david.keller.fr@gmail.com");
> 		
> 		signer.signPDF(inputDoc, outputPDF);
> 	}
> 2/ I resign the same file using the same method and in acrobat reader I have this error : SignDict/Contents illegal data
> I have googelized it, and I found only old topics for iText lib.
> I have tried the same with iText 5.X, and double signatures works
