A lot of mission critical systems are Java on the mainframe.
Not just Cobol.
Why don't people switch, then?
The mainframe gives you a predictible runtime.
Long running jobs don't get rescheduled or hogged by other loads.
I know about a firm that uses a mainframe to control a factory line.
The problem with replacing stuff that works (and the mainframe does) is then your job is on the line if the transition fails, and there are a lot of business moving parts inside.
