Yes, this part works, no problem.

Compiling from source code ... actually, I can implement rules in nashorn
JavaScript, but I'm pretty sure I'll get not serializable exception, but
I'll check this.

Referencing existing jar will not solve problem as I would need to
re-submit job, which I want to avoid in the first place. I actually wanted
exactly first scenario, send newly compiled objects.
