I've reviewed the steps here (many times), and I pool a number of Driver objects for my rendering. The only conclusion I could come up with was something with the precompiled xsl was causing my troubled. I only received this nullpointer exception when I pre-compiled my xsl documents into templates objects and tried utilizing these templates in a multi-threaded environment. When I go back to my old way of simply caching the XslSource's for each xsl document, I receive no errors when running multiple threads.
