animal-sniffer. And that would be fine for our -jre builds:
                   If we're building with JDK8, then clearly we're sticking to
                   JDK8 APIs. However, I assume (but did not confirm) that we'd
                   have the same issue with our -android builds, which need
                   animal-sniffer so that they can check that we're sticking to
                   JDK6-like APIs.
