I checked the code and it looks fine according to me. I see you are dealing
with RichFunction inheritance in wrapper classes. It is something that bothered
me too when I was working on the previous PR. Actually there could be a similar
minor issue in RichProcessWindowFunction due to duplicate code, however I
cannot see any easy workaround for it.
Regarding the overall feature, are you planning to do anything similar for
#2946 or should I reflect these changes also there?
