I think I kicked this intentionally to have a cached pointer to the wrapped objects for `EventBus`, `FileSystem` etc. Otherwise, they'd always create a new wrapper around the objects. I'm not sure how it works as they now should be all AnyVals  themselves, so maybe this is not creating objects anymore.

But if they don't create these Scala objects, I'm unsure whether we'd start to see leaks of the Java implementation... Maybe we should talk about this a bit in IRC when you have time.
