As of 06/02/16: I have a fish farm. As of the original date I have AFKed for about 3 days (while at work). This totals to about 30 hours. In that time I received an average of about 33-34 enchanted books. So 100 books. Out of those 100 books I was able to get a single mending book, and a single frost walker II book. So this is about a 1% chance. One would have to farm for about 30 hours to have a chance to get one or the other or maybe I am doing this wrong and could say 15 hours to get one or the other since I was able to get both in 30 hours. None the less you need a fully enchanted fishing rod to do so (luck of the sea III, lure III, mending, and unbreakable III)... and a lot of time.
So I can tell you it is currently working in 1.9.4; it is just VERY rare.
Also this is only true if Frost Walker and Mending have an equal chance. If they do not then I need to collect more stats.
