No aspersion on the M-F 9-5 programmers, Arne. But by definition M-F 9-5 
programmers have made a decision - not something I will heavily 
criticize - to confine their work to work hours, and keep their free 
time for family and leisure. As such they don't spend nearly as much 
time on off-hours professional education (if any), and we all know that 
work hours don't lend themselves to professional education either.

So my point really had to do with the fact that we often don't learn 
much new stuff on the job. Most of my career - for my M-F 9-5 
engagements - I've had to work on stuff that's well behind the power 
curve, because that's what clients use. I've yet to run across a client 
in my region that was willing to use JVM languages other than Java, and 
I expect I'll have the luxury of using Java 8 extensively maybe in the 
year 2016.

Let's also not forget, who has the time to focus just on Java or its 
ecosystem? I don't, and I spend way too much of my free time on software 
development. Only speaking for myself, but I also have to keep track of 
what's happening with other languages, and libraries, and tools, and I 
seriously don't have the luxury of examining the intricacies of Java 
bytecode. I doubt that M-F 9-5 coders do.
