Component-, Container- and HierarchyEvents are not always generated when needed

Now Component-, Container- and HierarchyEvents are generated
for component only when this type of event is enabled on it by a call to
enableEvents() or by adding appropriate listener. But we should
create these kinds of events if appropriate AWTEventListener is added on
Toolkit.
