Since OGNL 2.7, it looks like this dependency was introduced.
I'll ask to see if it's possible remove that dependency.

I guess this is due to  the move to OpenSymphony. There was even a very 
recent 3.0 release, so people *are* working on the project.

I observed that upgrading Spring made those issues disappear.

Couldn't this functionality be included simply in Velocity Core?
It looks that many web frameworks/projects are using it, and some do 
what Click does, other simply include VelocityTools JAR
