Maybe we could manually collect all these special contexts into an exhaustive list, make it available through some service. That would still not prevent possible post-festum collisions if we introduce new 'special' context mappings in the future - they might all collide retroactively.

>>> Another question is then how to deal with name collision when we detect them? We could detect them at GateIn startup time, or when adding a site or page through Site administration UI. We can disallow creation of conflicting name. That makes sense for portal names that conflict with mapped web.xml contexts. We could also just warn a user that name is in conflict, and the portal / page won't be reachable, but allow creation itself.
