Class c = this.pluginManager.Read(apps.get(sel.toString())); //Тут в методе Read работает Classloader. Срабатывает
Constructor constructor = c.getConstructor(); //Срабатывает
Object obj = constructor.newInstance(); //Срабатывает
KAProvider man = (KAProvider)obj; // Кастим к интерфейсу. Не срабатывает
А вот подгружаемый модуль:
Все методы в классе имплементированны с интерфейса KAProvider, конструктор т.понимаю не обязательно описывать.
