I think it's a good idea

And this is yet another myth. Java is NEVER used by any seriou scientist. Why? It's to slow. When your application is expected to run for weeks/months/years at a time every clock cycle matters.

Java is perfectly fine and well suited for what Java is good for. It is not now, nor will it ever be, a scientific programming language. That isn't a slight against Java. Christ you can probably write games in Java now..and the speed would be fine. But sometimes you need every last bit of speed possible...you know like the function were you have to write inline assembly to maximize usage of the SSE3 registers?

I guess I just tire of the C++/Java speed debate. In the real world if you need speed you use C/C++ combine with inline assembly. That's just the way it is.
