I don't believe that this is an attempt on Apple's part to hate on JRuby. I am however very curious about what impact this will have on the development of JRuby and other JVM-based languages, such as Clojure and Scala. It's no secret that a lot of folks in the (J)Ruby community work on Macs, but I think that bleeds over into the other languages' communities as well. For example, I'm pretty sure Rich Hickey uses a Mac, and a tweet from Michael Fogus earlier today suggests that he does as well. Not sure about the Scala folks, but I wouldn't be shocked to find out that they're Macheads too.

We'll have to see how this plays out. It's been very nice that Java's already available on all new Macs, but then there's been the dreadfully slow progress of incorporating updates, security fixes, and so on. On the other hand, OpenJDK has been building well on OS X for some time in both 32 and 64-bit forms. The only real missing pieces are easy ways to get OpenJDK builds installed (helped by Apple's restructuring of how they configure and locate Java installs) and the Cocoa-based backend for Swing (if you're using or building GUIs). In any case, there's lots of vectors to getting JDK/JRE on OS X, and this might actually make it easier to choose which vendor and version you want for your OS X Java install.
