Init code finishes before findAll and printlines get executed

Hi!
I'm running the example with the init code where the movies get put in the database on M6 and the application closes down before the findAll() and println get executed. I downgraded to M3 and everything works fine.
Leaves a lot of scary looking stacktraces in my log because the mongodb connections are already being shutdown when the findAll() executes.
