    Description

      I try to add a visible signature to a pdf file that is already signed with a valid signature, but the second signature invalidates the first one.

      I followed the example in SVN directory
      https://svn.apache.org/viewvc/pdfbox/tags/1.8.11/examples/src/main/java/org/apache/pdfbox/examples/signature/

      See the attachments.
