How is this supposed to work, if DocContainer.processMouseEvent() calls
Component.processEvent(), which should - according to the specs - call again
processMouseEvent() ? Why does it do so at all (since processEvent seems to be
the event type dispatcher in JDK)?

Since processEvent() is protected, it can be called from all derived classes
(outside of java.awt), for any event (i.e. not just for the ones obtained via
EventQueue.getNextEvent() / dispatched via EvenetDispatchThread()). According
to the specs, processEvent() has to call the process<EventType>Event() method.

Wait a second - isn't the ICE web-browser based on swing? This would explain a
