[jira] [Comment Edited] (PDFBOX-3244) New signature invalidates previous signature

    [ https://issues.apache.org/jira/browse/PDFBOX-3244?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15158405#comment-15158405 ]

Here's a file where I did the second signature with the CreateVisibleSignature example (from 2.0) and I don't get the complaint in Adobe Reader. So there must be something different there.
