I took the liberty of starting down the road of this described approach.
I’ve gotten it to the point where all of the core modules compile (haven’t
taken on extensions or community modules) against spring 4.2.5 and spring
security 4.0.4. Haven’t actually run the server or any tests yet.
https://github.com/jdeolive/geoserver/tree/spring4-upgrade
I think the next step would be to merge this with andreas mockrunner branch
and go ahead and perform the servlet api upgrade. With that done I think we
would be in a position to start working through all of the unit tests.
