Ok, I'm closing this vote with 8 +1 : Colm, Felix, Kiran, Lucas, Pierre, Shawn, Stefan and me.
Colm, Pierre, although I was in agreement with your suggestion, the fact is that we don't anymore support Java 6 as a running JVM for ApacheDS (Stefan has tested it and many tests are failing). We will then switch to Java 7+ only for ApacheDS and teh other projects. Many thanks !
