JRuby support about rerun HOT 3 OPEN

I don't know much about JRuby, but if it doesn't support fork then I doubt there's much rerun can do. Fortunately, rerun is independent from your own JRuby app; you can install multiple versions of ruby on the same system and use one for rerun and the other for your own app(s). I see you're using rvm so I bet there's a way to ask it to run rerun with an MRI Ruby, something like

rvm 2.3.2 do rerun --dir config --pattern '{*,.*}' bin/daemon

(Assuming you have a ruby 2.3.2 in your rvm list.)

Please let me know how this goes.

Why a fork is needed to execute a separate process? Isn't a thread with Process.wait enough?

Oh wait, v0.11 was before we switched from fork/exec to spawn. Can you try with the newly-released v0,12?
