> Currently the class `ProcessManager` will add a shutdown hook to stop all the
> living processes before JVM exits. The shutdown hook will never be removed.
> If this class is loaded by the user class loader, it will cause the user
> class loader could not be garbage collected which causes meta space memory
> leak eventually.
