1.2.2 flipped to jQuery 1.10.2 and it was resolved slightly before that IIRC -- the screenshot shows it trying to load 1.10.1 so that's definitely not 1.10.2.
What I meant is that in 1.2.2 the browser is trying to load jquery-1.10.2.min.map and succeeds with a 304. Maybe I am confused by your answer as I assumed that you meant no .map file will be loaded.
