The Digester version I was using is unclear, but I'm sure it's a year or
two old. It's from before the time the version number was in the name
of the jar file. I updated Digester to the current version (1.8) and
tried again, with basically the same results:

My Velocity tools is on 1.1. I see there is a link to a released 1.2
version of velocity tools on the Velocity website:
http://velocity.apache.org/tools/releases/velocity-tools-1.2/index.html
I'm willing to upgrade, but the download link is currently broken.
