> Hi,
> I was experiencing runtime exception(s) with tomcat 7 (not with jetty), with a simple quickstart (nothing special in the quickstart).
> I had these errors when I start (or restart) the server and reach the homepage. One time the first error, next time the second error, etc.
> I am not sure how I can reproduce this outside my dev env (eclipse + tomcat)... Also, to be honest, it does not repro today (tried both M1 & SNAPSHOT) but... I have seen same errors while testing at work (tomcat 7.0.23).
