Code Review & Fix J2SE / JEE code that uses iText PDF To Optimize Memory use and any other bugs / issues. This project is for some one with experience in iText pdf library. We have written a J2SE code (by using iText) to convert from csv / mysql .database to pdf etc. This j2se code is also going to be used as a library in our JEE / jsp, spring, mysql web application. We like you to do a code review to find out what all places we can optimize / handle memory leaks / garbage collection in java etc etc or any other bugs / issues.
