(Sorry, posted this as a comment by accident!)
OK, so the first thing I thought when I read this thread was "Why on earth would they be using an ancient version of iText" -- but having looked at the AGPL (which I'd heard of, but am not familiar with), NOW I understand why.
So, the next logical question is... It seems that there weren't many (or ANY) iText alternatives when this question was posted over three years ago, but maybe Apache PDFbox might work now? Any thoughts about adapting Jasper to use it? The Apache license is much more permissive than the AGPL.
