Oh, and I suppose this is a great time to gloat: if Java 9 turns out to be a dud, there's always Scala and Kotlin as interesting alternatives to continue the general Java platform. Depending on how this goes, it's even possible that a company like IBM or Red Hat will fork Java into a new language. Then, after a few years of fragmentation, Oracle gives up and donates it to the ASF after it's already irrelevant.
