As the title, I used Tomcat 7.0.62 as contents.
I think the suggested Play2WarKeys.servletVersion is "3.0".
But if I use 3.0, the response of Application will be strange, such as twice response happen towards one request.
If I use 2.5, the application will work well.
So I have a question that whether it is OK if I use a 2.5 servletVersion on Tomcat7.
