Github user miguelaferreira commented on the pull request: https://github.com/apache/cloudstack/pull/761#issuecomment-136095882 @remi: passing null to a method or returning null from a method is always a bad choose. There are better ways to express "I don't know" (e.g. Using Optional<Boolean> in this casa). I understand the intention of your change, but it addresses the symptom, not the problem. The problem is most likely in how the return value is handled elseweare. Please reconsider this change. If it's a blocker we can work on fixing structurally ASAP.
