No there is not a reason. We simply not updated it from 5.4.0 - since it was not really used. But there is any reason to not use it in production. The only difference between tomcat and jetty distribution is that one is using tomcat as web server while the other one is using jetty..
In ECR (the core we will contribute to Eclipse) we are indeed using jetty by default. But anyway ECR is not yet integrating Nuxeo JSF UI. (and jetty is not integrated as in Nuxeo - it is integrated through HTTP OSGi service) --- Mailing list: [email protected] Forum: http://forum.nuxeo.org/f/1/
