Lately we've given up that Sun is interested in solving this, and instead started to look at writing some crazy classloader that could emulate this for you by recompiling objects, tracking references to objects, and using reflection to copy over changes. Not sure how possible it is. This is exactly what I was trying to solve with WebWork's "prototype" feature -- it works great until lame libraries (read: Hibernate) hold on to objects/class definitions longer than they should. Then it's game over: time to restart your app. To those who think reloading the webapp is an option -- heh, you'll sing a diffirent tune as soon as you have to deal with an app that takes a long time to start up (for whatever valid or invalid reason).
