Can you paste the the entire error trace on here?
Hmm everything looks ok from what I can see....
Can you run the clean target on your ant file to make sure that there are no previous class files in the exploded-* directories? Sometimes I get 'class residue' from the previous builds and it holds on to definitions that I removed from a while back.
I didn't see a field in Author called 'Author' and you may have had it previously and it just didn't get cleaned out.
