While I am no fan of Java the language myself, there is no reason for schadenfreude. I would like to see Java survive, if only because of its virtual machine (and Jython, Clojure, JRuby, etc).
Probably no reason that Clojure and Scala can't be ported to their own VM, especially with Clojure's self-hosting push. Yeah, the JVM has a lot of libraries, but the libraries will follow the developers when the dead-ness of Java starts getting in the way.
