Plutext

Hi! I have a few pptx files that should be merged, but I am unable to do it in Java. Online merger fails to merge the files too. The problem is that these pptx files have custom themes to add watermarks etc. I am using Plutext Enterprise 3.2.0 trial version.
I have attached stacktrace to the post

As per my email to you, https://github.com/plutext/docx4j/commi ... dacffa20cc
fixes that.

To try it, replace your docx4j jar with:
