Loading modules at runtime

[Piotr Chmielewski]

For one of my projects, I decided to create "plugin" system to load 
class at runtime from JAR files. Currently, I load each plugin using 
URLClassLoader.

With arrival of JDK9, is there any plans for loading modules at runtime 
(or is available already for testing in build snapshots)? For example 
instead of:

String pluginPath = "CPU_Monitor.jar";

URL pluginUrl = new URL(pluginPath);

URL[] urls = {pluginUrl};

URLClassLoader urlClassLoader = new URLClassLoader(urls);

Class<?> pluginClass = 
urlClassLoader.findClass("com.example.cpu.monitoring.Monitor");


Would be possible to use something like this:

Module pluginModule = ModuleManager.getModule("com.example.cpu.Monitoring");

Class<?> pluginClass = 
pluginModule.getClass("com.example.cpu.monitoring.Monitor");


I guess that something like this could be implemented as library outside 
JDK, but such API could be great addition to Jigsaw.
