> We are using xalan 2.7.0 and fop 0.95 for generating PDF reports.While generating pdf report for a large xml string of 2,96,126 characters(~ nearly 3 lakh characters) ,the PDF generation fails and it fails at transformer.transform() method in TransformerImpl.java.Since in our product,we need large reports with very large strings(events),we need this fix ASAP.
