These are always the questions that are hard to resist :-( I’ve created a simple proof of concept to show how you could use [Vaadin with OSGi][1]. Vaadin is one of those (in my opinion horrid) pieces of software that can’t resist the temptation to use statics, singletons, global variables, and strings instead of classes :-(
In my opinion good software is _instance_ based and OSGi is a prime example. So
it took me a few hours but I figured out how I could trick Vaadin in letting
the service create the instance of the UI and not through newInstance().
The provided repo has a readme. Let me know how it works and I am of course
very interested in PRs since this is a quick POC and not the usual quality.
Quick note. The Vaadin dependencies use the new Maven Bnd Repository plugin in
3.2. Look at cnf/vaadin.bnd for the specific info.
Kind regards,
Peter Kriens
