Major Description
Installing the war feature directly works but if the http-whiteboard feature is already installed I get the exception below. We had a similar problem some time before when whiteboard and war referenced different versions of pax-web. But this is not the case here.
The problem can be avoided by using the working order but it would be good to fix it for 2.2.7 if possible.
Start from a clean Karaf 2.2.6
karaf@root> features:install war
