I use fop as part of a build script for a project I'm working on. Today, I noticed that part of my build was not working. I figured that something must be wrong with the fop package I downloaded for use in the project, but then I noticed the same error is happening with fop as installed via pacman. The only thing I can think of that would have made a difference was the fairly recent jdk update. Searching for this paticular error brings up results from over the last few years, but none of them seem to have any resolution. They refer to it as a "warning," but it is definitely stopping execution of fop.

I ran into the same problem and had to roll java-batik back to 1.7-12.

Thought I would update this just in case anyone stumbles upon it.
With the latest version of fop and batik it almost worked out of the box. Just had to link xml-apis-ext.jar -> xml-apis-ext-1.3.04.jar in /usr/share/java/batik.
For reasons I don't know, they have started to include the version in the file names but not in /etc/fop.conf.
