[jdom-interest] fail to output Document to encrypted file

[Phill_Perryman at Mitel.COM]

I use the following in my extended document to serialize itself

      XMLOutputter serializer = new XMLOutputter();
      FileOutputStream fos = new FileOutputStream(file);
      CipherOutputStream out = new CipherOutputStream(fos, pbeCipher);
      serializer.setOmitEncoding(true);
      serializer.setOmitDeclaration(true);
      serializer.output(this, out);
      out.flush();
      out.close();

XMLOutputter does not close the stream. You should try :

       OutputStream os = new CipherOutputStream(                        new
FileOutputStream(catFilePath),cipher);
       outp.output(doc, os);
       os.close();
