I don't think upgrading is an option as
Ognl has dependencies on Javaassist
Since OGNL 2.7, it looks like this dependency was introduced.
I'll ask to see if it's possible remove that dependency.

and the project
development is quite obscure.
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.

2. Drop ConcurrentReaderHashMap and use JDK5 ConcurrentHashMap. I know there 
were concerns raised
wrt Spring but it isn't clear what those issues are. We can always revert once 
we have more details.
+1.
I observed that upgrading Spring made those issues disappear.

3. We should rename WebappLoader as it can have the same issue as #1 if 
Velocity Tools is included
in a Click project.
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
- but mostly just for this single class.

Thank you,

Adrian.
