all my constructors are private => no subclass

%% My experience: FTTPCktLoader is a singleton with a single constructor, which is private. I struggled but failed to extend the class.

Look at the post on onion. Visualize the “onion-shaped” constructor call stack. Subclass instantiation MUST attemp (and fail) to call my constructor.
