Email notification on Comment Edited event contains a stack trace exception if the comment previously had a security level applied and the recipient of the email couldn't view the original comment

XMLWordPrintable

      andreask@atlassian.com picked up on what was going on here, from his comment on the support case where this was discovered:

      • Add a comment with a security level that certain users are allowed to see and other users aren't allowed to see due to the security level (those other users should have permission to browse the issue though!)
      • Edit that comment and remove the security level. We should now send a notification to all users with browse permission, including the ones that didn't have permission to see the comment previously due to the security level that was set
      • The null pointer exception occurs I think because we remove the originalcomment from the velocity context for users that didn't have permission previously to see it. When we try to diff the original comment with the new comment for those new users we get a NPE since the original is not provided.

      The diff to the previous comment shouldn't occur if there's no original.

      The stack trace in the logs looks like this:
