I didn't know about the native implementation! But my point was a more general one. If I have an old fortran numerical library that I want to pull into my analysis.

My experience of most big data projects is that a lot of it involves writing some scripts to do some data munging, and then plug it into some existing library for numerical analysis. The JVM is a good piece of software and supports an amazing ecosystem. It's just not that easy to break out of the ecosystem. Of course, this might just be because people haven't tried enough. I think that the lack of syntactic flexibility of Java made it problematic in the past. Now with languages like Clojure or Scala which have at least as much of flexibility as python (more in fact), perhaps this will change.
