According to JEJ, it is him. Supposedly, it was recorded for the previous film. Also, the Death Star always rotated. It's even a continuity error, as they couldn't decide which way it should rotate(if at all). You missed the new docking bay 327. Also, JEJ getting credit was bad in my view. Jones specifically requested that he not be listed in the credits. He sees himself as a special effect. Adding him goes against his own wishes.
The general sound remix stunk(Chewies rifle in the detention block was the same as an AT-AT chin gun).
