JoltModelAndView: If you forget to set jolt_view = true through the annotation, you get an NPE

[Verdoso]

If you return a JoltModelAndView but you forget to set up Jolt usage through the annotation in the application class, you get a NullPointerException when the SummerJoltView class tries to read the JoltViewConfiguration... that is not there because it has not been loaded.

It's a developer mistake but the app should break in a more meaningful way with a clearer message.
