Hey Guillaume, looks nice. I'll try to benchmark it against the famous Akka Pi.scala example.

Btw since, language is not important, why didn't you write this in Scala?

I had only 2 years of experience with Scala and was not always able to foresee the overhead of various language constructs. As this was my first project where I considered performance critical, I decided to stick with Java--with which I have decades of experience and a more in-depth understanding.
