The X-Atmosphere-Framework parameter reveals a concrete implementation (version 2.2.13.vaadin3-jquery) which has been pointed out in a security audit as something one should avoid (or remove, in our case). (By the way, Vaadin has others, e.g. https://skip.dot.com/app/VAADIN/vaadinPush.js?v=7.6.4)
My question is whether it's possible to configure the application to use another framework. Or if there's an entry point we could implement to avoid passing around of version numbers? Has Vaadin been updated to use a newerversion of Atmosphere, as 2.2 has already reached "end-of-life" (https://github.com/Atmosphere/atmosphere).
