Trying to set process title gives an error:

# jruby -ve "Process.setproctitle('myapp')"
jruby 9.0.5.0 (2.2.3) 2016-01-26 7bee00d Java HotSpot(TM) 64-Bit Server VM 25.72-b15 on 1.8.0_72-b15 +jit [linux-amd64]
NoMethodError: undefined method `setproctitle' for Process:Module
  <top> at -e:1

It should either be implemented or NOOP with a warning.

I'll mark it as not implemented. It's difficult to implement across platforms even from C, and from Java it's going to be nearly impossible.

It looks like MRI marks it as noop and doesn't report an error on platforms where it is not supported.
