Peter, Thanks for the suggestions! The error came back after I continued building that page and one of your methods did work. I tried upgrading javassist but that didnt relieve the error and I am using jetty through eclipse with no try/catch blocks. Finally I removed the block of my code that seemed to be erroring out into a private method and everything works fine. Obviously not ideal but it will work until t5(or javassist) is a bit more stable in this area. Thanks!
