How do I restart the whole JVM in our Windows Server which have JRE, without restarting the OS?
Is there something like:
java -restart
Or this is not possible. The idea is that I added tool.jar in /lib/ext folder of the JRE and that I need to restart the JVM.

jar in /lib/ext folder of the JRE and that I need to restart the JVM. There is nothing like a JVM running in an OS. Instead several independent instances do run. Just make sure to stop all running Java applications (java*.exe) and restart them if necessary.
The way to start a jvm is by invoking the main, either by invoking a jar using java -jar MyJar or by simply running main class from an IDE. Yes, Multiple jvm instances can be run on a single machine, they all will have their own memory allocated. There will be that many jvms as many main programs you run.
The Java process runs on demand as and when you want to run it. It's not a daemon. You need to stop the Java process manually (kill it) if it doesn't end gracefully.
