> Hi
> I have made the following modifications to avoid ClassCastException or NullPointerException
in addSignature(PDSignature sigObject, SignatureInterface signatureInterface, SignatureOptions
options) :
> {code}
>                         // Appearance Dictionary auslesen und setzen
>                         // MOD_CS

>                         // ap.getDictionary().setDirect(true);

>                         COSBase item = cosBaseDict.getItem(COSName.AP);
