[jira] Resolved: (WW-2372) hidden Velocity dependency?

["Don Brown (JIRA)" <ji...@apache.org>]

Don Brown resolved WW-2372.
---------------------------


This is by design, as it allows us to support Velocity results, but only if the Velocity jars are available.  The message is logged at DEBUG since most users won't have it enabled for development and certainly not for production.

> Hi,
> Following the guidelines in http://tomcat.apache.org/tomcat-5.5-doc/logging.html, I discovered that Tomcat logs this exception when shutdown:

> I'm not using Velocity in my app, but it seems to require it anyway (in the docs velocity is marked as an optional dependency though). 
> The above stack trace goes away if I add the velocity and velocity-tools jars in my app's WEB-INF/lib folder.
