Tomcat 7.0.6 is going to require some work to integrate properly. At the moment, we're going to see errors like the following:

Tomcat's new ClassLoader MemoryLeak avoidance code is using a temporary thread to configure/initialize the event listeners for the Context. So, things like JNDI and OpenWebBeans aren't going to work. 

There isn't a switch that can control this Tomcat behavior. Nor do I see anyway to hook into the Tomcat processing to hook into this processing. Our best hope would be to add some additional integration code in our externals code and work on pushing this into Tomcat.
