I use Tomcat in production.
Are Jetty and Winstone (https://stackoverflow.com/questions/1515654/what-is-a-lightweight-fast-java-servlet-container) suitable for production use?
I'm happy to let go of features in return for simplicity. Servlets and filters are probably sufficient and the server isn't heavily loaded, so interested to experiment with running it on a minimalist platform. Sticking with Tomcat is also fine.
