Does the problem persist if you serialize the SAX events generated by
the Incident with an identity transformer to a file and run the XSL
transformation stand-alone from the command-line?

I don't think it's a problem but did you realize that you have two FOP
processing runs in your testGeneratePDF() method, the first started by
Transformer.transform() and the other by input.run()? Since I can't do
anything with the line numbers in the stack trace, this is something you
have to do.
