I'm not a real orbital dynamicist but my understanding is that the L4
and L5 points in the Earth-Moon system are unstable because of the
influence of the Sun, thus this is not a genuine two body system. The
Sun-Jupiter L4 and L5 points are stable because no other body in the
solar system is large enough to disturb them. There are in fact a group
of asteroids parked at each point. The L1, L2 and L3 points are unstable
in any system and satellites parked there require fuel for station
keeping.
