Description

I tried to remove ID from a PDF file using PDFBox. Any of my attemps haven't resulted in ID being removed. Please have a look how I tried to do so:

if ( document.getDocument().getDocumentID() != null ) {
// 1. doesn't work
document.getDocument().setDocumentID(null);
//2. doesn't work either
document.getDocument().getTrailer().removeItem(COSName.ID);
// 3. doesn't work
final COSDictionary newTrailer = document.getDocument().getTrailer();
newTrailer.removeItem(COSName.ENCRYPT);
newTrailer.removeItem(COSName.ID);
document.getDocument().setTrailer(newTrailer);
// 4. doesn't work
final COSArray documentID = document.getDocument().getDocumentID();
documentID.clear();
document.getDocument().setDocumentID(documentID);
}

Who I can send a source PDF to?
