Thanks all for you responses!!! Actually currently we are facing some problem with current version of JBoss4.0.2 and hence we plan to test our application with upgraded version. Now Just for upgrading JBoss i dont think i will get permission to change entire JDK version itself as we may need to do lot of testing before we upgrade that. So was interested if any workaround.
