Close, you do need to stop the world every once in a while to GC some of the harder stuff.
But it's true, there's flavors of Java that are certified for hard realtime. If you stop the GC for 100ms every 2s regardless if you need it or not, that's pretty nice and predictable behavior for a realtime system.
