The error message is created by the forked Ant process, not the one
executing the build file.  You would see the same if you used

ant -Dbar=${bar}

(with proper shell escaping in place, that is).  Properties specified on
the command line via -D and -propertyfile can now use other properties
in their values.  Prior to Ant 1.8.2 they were not expanded.

What you see really is a border case that only happens because you use
the same property name in your build file and the property use pass to
the forked Ant process.

I'm not even sure how to document the situation 8-)
