Hi guys, so I was playing with concurrency in jruby and found some weird
behavior that I don’t understand. Here is gist with code sample and
description: https://gist.github.com/Gonzih/f62ccc35a9d4d8d23ba0 in
short issue is that if I call proc from inside instance of Callable I
can’t do any wrapping around this call (callbacks, error handilng and
etc). Can someone explain to me what is going on behind the scene?
