Fair enough, but the new method doesn't declare "throws X". I know
technically speaking you don't have to declare runtime exceptions but I
think it is useful in this case.
I am actually using the Guice-2.0 snapshot which doesn't declare the
exception either in code or Javadoc. I can see the trunk version at
least added it in the Javadoc (though a different exception!)
Anyway, as soon as trunk is usable (right now I'm getting exceptions at
runtime which I mentioned in a separate post) then I'll build an updated
snapshot and use that...
