Gracefully start/stop JVM instances. An alternative to fooling around with kill commands and pidfiles.

"com.github.malliina" %% "jvm-control" % "0.1.0"

During app startup, please call com.mle.jvm.Control.startSystem(onStop = ???), passing some code to run when the system is eventually stopped.

To stop the app, run main class com.mle.jvm.Stop or call (from another JVM) com.mle.jvm.Control.stopSystem().

Control.startSystem() starts a listening actor that accepts messages from other local JVMs. Running com.mle.jvm.Stop starts a JVM and creates an actor that looks up the listening actor and sends it a shutdown message. Both parties will then stop.

SSL with client authentication and proper file permissions should prevent any local JVM from potentially stopping any another local JVM.
