In Star Wars: The Clone Wars episode Point of No Return, M5-BZ sacrifices himself by ejecting buzz droids and himself into hyperspace. An organic being would be atomized but BZ is mechanical. So what would happen to him? Will he drift in the superluminal tunnel for all of eternity?
Since the droid had no such generator, ejecting into the hyperspace would either destroy it, or drop it into normalspace far from any celestial body (effectively stranding it forever).
I'm not aware of any canon info to further clarify which of the two options would happen.
