Bull.... I just remembered that we've had this before:
http://fop-users.markmail.org/search/?q=PDFNumber+not+empty
Back then it was suggested that it could be a multi-threading problem
but looking at what the exception raises tells me it has nothing to do
with the (still unsolved) issue with DecimalFormat. That code is just
hanging around there. But then, without being able to reproduce the
problem here, I don't really know what to do. Maybe someone else has an
idea.
