Hello again, I think I may have found the issue. In Splitter.processNextPage it sets the resources using page.getResources(). I think it should be page.findResources. I guess the sample pdf I had did not have the resources on that page and it's required the go up the hierarchy.
Is there a reason why findResources was not used in the first place, that would invalidate this fix? In the comment of getResources it says you may want to used findResources.
