o.getClass().getMethod(...) is an anti-pattern for finding a public
method. Object.getClass() returns the implementation class while you
want to invoke a public method `javafx.collections.ObservableList::add`
in this case. In this case, the declaring class of the method is known
and so one way to fix it is to use the specific Class:
Class<?> observableListClass = javafx.collections.ObservableList.class;
m = observableListClass.getMethod("add",new Class[] { Object.class, });
o = m.invoke(o,new Object[] { button1, });
