I know of one investment bank (a former employer) that rewrote its mainframe-based settlement system in Java (on Linux). Front office systems were often Java (replacing Obj-C in some cases).

That was two decades ago – almost a generation! Interesting to think that some of those systems would now be considered “legacy”.

I'm guessing Swiss Bank/UBS as a mate used to trade there and had a NeXT workstation and loved Wingz. Later I heard they were doing server side pricing work on Apple servers. I stand corrected; thanks!
