Servlet spec requirements?

[bviktor]

CentOS comes with Tomcat 7, and that doesn't seem to satisfy the requirements for Para:

What is the required Servlet spec revision to run Para?

For the record, this one wasn't actually resolved, there were other JARs and various other errors in the Tomcat+WAR setup, I just didn't bother any further.

Deploying to Tomcat 7 is problematic. Tomcat 8 is the minimum supported version.
