              The issue is related to our new support of form widgets. In particular with the AbstractWidgetAnnotation class. There are a couple digital signature placeholder fields on the page that do not have an appearance stream which is the root of the null pointer exception and painting errors.

              I have small null pointer check for this corner case and hopefully soon we'll be able to add the signature if needed.
