Struts Validator doesn't seem to be working

I'm wondering what I'm doing wrong. I tried dropping last nights build
(20020930) of struts-validator.war into Tomcat 4.1.12, and it does not work
at all.  Is this a known problem?

The index.jsp page contains the following message in red:
ERROR: Validator resources not loaded -- check Commons Logging logs for
error messages. 

So I looked into it a little and noticed in Tomcat's log that a FastHashMap
is throwing a ConcurrentModificationException:
