 * Custom {@link NativeJavaClass}. The goal is to get access to some {@link NativeJavaMethod} properties that have
 * package visibility for better help and auto-completion.
 * We could redefine entirely how a java object gets wrapped, in order to have our own method representation,
 * but that is not easily customizable (too many static methods involved).
 * What we can do is customize what our {@link NativeJavaClass} returns when a method is requested through the get method
