-     * The idea of this method is to define, which classes are considered as platform classes. This is important to know
-     * to avoid potential class loading issues during the load of a NeonBee Module. Because generally a class which is

+     * called) module class-loader. This way, you can prevent incompatibility issues across modules and also have
+     * modules with a much smaller runtime footprint.
