Vaadin Spring session serialization

Hi folks, 

I've been testing on a small project VaadinSpring integration and I'm having issues with the session serialization when reloading/redeploying the application on Tomcat. 

I'd be great that the session is serializable to provide HA but also enable faster development as the "compile on save" can save lots of time. When using spring boot it can take 10 to 16 seconds for the app to reload and that's a lot.

The object which cannot be serialized is: com.vaadin.server.VaadinSession.springVaadinServlet. But, the strange thing is that according to the article https://vaadin.com/blog/-/blogs/vaadin-spring-1-1-is-out the session should be serializable now. I have all dependencies updated.

Best regards,
Alex Roig
