I think this can happen when your Ivy cache gets corrupted, and can be fixed by clearing the Ivy cache, triggering a re-download.
(To automate this, we could wrap the <ivy:cleancache/> ant task: <http://ant.apache.org/ivy/history/2.2.0/use/cleancache.html>.) Steve From: Smiley, David W.

Any ideas? ~ David
