Java 6/7 Performance Comparison

Hey, I've been using ObjectDB for a small scale home project to gain some familiarity before proposing it in a commercial project at work. What I've noticed though is that when using objectdb in embedded mode based on the console tutorial, there seems to be a bit of a performance gap running the same code between Java 6 & 7 Tracing it through I can see the bottle neck seems to be at the creation of the entity manager and I was wondering if there are any additional configuration options I may have missed while running under java 7. ... We couldn't reproduce the problem in our environment using your example with Java 7. ...

Project runs in Eclipse but not when exported to runnable jar
