Summary: NullPointerException

Initial Comment:
When I compile all files when having several files
open, but one is an untitled non changed file. It ask
if I want to save this file. I say choose not to, and I
get this NullPointerException!
It doesn't happen everytime, but on occassionally.
This is from the newest version of drjava from the CVS.
