Interesting, I've never run into this. Under what circumstances 
did you encounter the directory "Program Files" not being mapped to 
"PROGRA~1"?  I figured that since the directory it is put in place 
during an install, it would always be this way, except possibly 
on customized installation.

Yup, that would do it. Good call. Fortunately for us, jdk1.6.0_07 has no 
spaces in it, so Condor won't be get confused in this instance :)
