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

IBM's JVM has a feature called "resettable" which allows you to effectively do what you are asking.

Other than the IBM JVM, I don't think it is possible.
