    Seems the session cannot be serialized or deserialized because it refers to a JSONObject. Can't find any place in Vaadin where a JSONObject would be put in the session though. You might be able to get more information by adding 

    
-Dsun.io.serialization.extendedDebugInfo=true

    when launching your server.
