NoClassDefFoundError: org/bouncycastle/asn1/ASN1OctetString #8

For certain kinds of PDF (containing signatures?), iText needs to have the Bouncy Castle crypto library available. If not, batesmaster will crash with an exception:

  Exception in thread "main" java.lang.NoClassDefFoundError: org/bouncycastle/asn1/ASN1OctetString

An example PDF that exhibits this behaviour can be found at http://www.deutsche-rentenversicherung-bund.de/cae/servlet/contentblob/33740/publicationFile/16757/C5001.pdf

Just adding bouncycastle to the classpath unfortunately does not solve the problem. For the above sample PDF, you would just get the following instead:

com.lowagie.text.exceptions.BadPasswordException: PdfReader not opened with owner password
at com.lowagie.text.pdf.PdfStamperImp.<init>(Unknown Source)
at com.lowagie.text.pdf.PdfStamper.<init>(Unknown Source)
at com.batesmaster.batesStamper.ProcessDoc(batesStamper.java:162)
at com.batesmaster.Main.main(Main.java:145)

If it is really not possible to stamp the PDF, batesmaster should output an appropriate error message.
