Could be simpler, but LGTM.

This seem overly complicated. Try this:

  return Isolate.spawnUri(...)
      .then((Isolate isolate) { 
               throw "Created isolate from missing file.";
             }, onError: (e) {
               print("An error was thrown as expected");
             });

We talked about this, and I was surprised that it would work.  I think most
people would be surprised, so I prefer keeping the more verbose version.
