Odd Duo Exception after upgrading to 3.3.0 from 3.2.0

We had a similar error that we fixed by updating our customized web.xml 
file from 3.2.1 with the new version in 3.3.0 and reapplying our 
changes.  We did *not* have to add the classpath settings that the Duo 
module doc installation recommends; 3.3.0 already has those paths included.
