> BundledJarRunner attempts to load the main class using Class#newInstance. The call to newInstance will then attempt to find and invoke the class's zero-args constructor. This will throw an InstantiationException if there is no zero-args constructor to be found.
> Loading the main class is unnecessary. Since main is always static it can be invoked with a null target object.
