:)) Sorry if I used the wrong word. I mean restart my JVM. Since each app will be allocated some JVMs, which run on some servers, I wonder if I can reboot them. It is not an ideal solution, certainly, when you are talking about error-tolerance and scaling. However, during some phase of development, the behavior of your app become unpredictable on someway and we need a way to reset the app to get to certain stable state or try to figure out the problem.
Deploy a new version can restart my JVM? May be not. Recently, I get an VerifyError error while my FreeMarker engine try to instantiate a class named FreeMarkerJspApplicationContext. In subsequence request, FreeMarker always throw java.lang.NoClassDefFoundError (without any reference to VerifyError), so I guess GAE JVM some how "cached" the class definition. I modified the version number and redeploy and guess what, the behavior of FreeMarker engine is just like the JVM is never restarted. I tried after 10 hours and now it is showing VerifyError. You just never know, 'till you jump into the mess. I believe such feature is "nice to have", though.
