Hi, I am new to the deployment aspect of Vaadin. I am using the Vaadin maven archetype to build off of. After building the application and deploying it to my remote Jetty server, some of my users have noticed that data is persistent from previous users. My assumption is that anytime a user visits the application a new session/instance is created. Is there something I am missing in the configuration of Jetty or is it another issue all together?
