With my "beyond complex" application, redeploying the entire application uses way too much permgen space and after the first redeploy I am using 324 meg of pergen with a total jvm size of 764 meg. Add that to my db, IDE and application, I run out of memory at 2 gig pretty quick. There are several parts to our app that are less than desirable for development, including several class caches baked in at several layers. I can't re-architect the application for an improvement in development only. So, I have tried the links mentioned but they don't help with my use case. I really need the hot redeploy of one class to work to eliminate the redeploy pain. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3983463#...
