After some more digging, I see that the "camel-test" artifact references the "org.junit.rules.TestName" class, which in some older versions of Junit (4.12 for instance) extends a "TestWatcher" class, although in newer versions that is changed to "TestWatchman". I still can't figure out the root cause for this.
