The JVM allows commercial software to be usefully cross platform. If you are working with open source or scripting/jitted/non compiled languages this doesnt matter. Compiled C or C++ code was hard to get for the right architecture and work with.

But it makes no difference for open source, hence the Linux coders disdain for VM languages, and it makes no sense with Python or Ruby where you interpret the source. And native JIT makes more sense now, the JVM being a bad language to write a JIT compiler for, as it loses a lot of important information.
