Any way to “reboot” the JVM?

Question

Is there any way to reboot the JVM? As in don\'t actually exit, but close and reload all classes, and run main from the top?

Answer 1

If you're working in an application server, they typically come with built-in hot deployment mechanisms that'll reload all classes in your application (web app, enterprise app) when you redeploy it.

Otherwise, you'll have to look into commercial solutions. Java Rebel (http://www.zeroturnaround.com/javarebel/) is one such option.
