Fine.

How does the new API help? Is it really necessary for the code to 
specify the command shell
(command.com or sh)? For Windows, if I use the new API, do I need the 
temporary files anymore?

I'll look into it. I'm not sure about the compilation part. If I use 
reflection on java.lang.Runtime
to see if the new method exists, then the code will compile fine with 
pre-1.3.
