* Since Java SE 9, invoking getResourceXXX on a class in a named
* module will only locate the resource in that module, it will
* not search the class path as it did in previous release. So when
* you use Class.getClassLoader().getResource() it will attempt to
* locate the resource in the module containing the ClassLoader,
* possibly something like:
* jdk.internal.loader.ClassLoaders.AppClassLoader
* which is probably not the module that your resource is in, so it
* returns null.
*
* You have to make java 9+ search for the file in your module.
* Do that by changing Class to any class defined in your module in
* order to make java use the proper class loader.
