Test failure on the current master

There is a test failure on the current master (fetched from github
today). Oddly enough, this failure occurs only when I run the tests
from the console, using maven (mvn clean install). The test does not
fail when I run it in Eclipse, which makes me think it might be caused
by some sort of interaction between tests.

I'm not familiar enough with the code, so I'm giving you guys a heads
up. Here is the stack trace:

Hi Nicolas,

thanks for the heads-up! I forgot to push some commits to github, so it should work now. Let me know if it doesn’t.
You’re right, there is some test influencing another. A UnitOfWork is started somewhere, but not properly stopped. I didn’t take the time yet to figure out in which of the 600 tests it is.
