Description

This will not revolutionate performances alone. We will win between 1 to 4 minutes.

But we win as well:

• it's a step for parallelizing the tests
• new tests are less expensive as they do not create a new jvm: it's a continuous win
• it will allow to push it on dev env while having the same env on dev & on build, and 3 minutes are 10% of small + medium tests execution time.

I will do a few "submit patch" to see if it works well before asking for the real commit.
