Does Bamboo run the example tests as well? If yes, than the exception may be due to some other changes.
I'm afraid the bamboo errors have to do with something else. All tests (at least from the Wicket core project) run fine in both Eclipse and maven. I think Bamboo is messed up somehow. See http://wicketstuff.org/bamboo/browse/WICKET1X-WICKET-120 Eelco
