Does the continuous build work?

Hi, Jeremi told me that I may have introduced an error in my refactorings. I'm sure this is possible even though my local build says "build successful" because the tests are all failing. That said, I've also noticed that the continuous build has also said "build successful". Thus I'm questioning whether the continuous build is actually failing in case of a build error. Jeremi says that if you run a xwiki built from the trunk it won't display any page because of an issue with web.xml. Is that not tested in the automated build? Thanks -Vincent
