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.
