java.lang.IllegalStateException: UT000071: Cannot add path template /{param2}, matcher already contains an equivalent pattern /{param1}

      If both registrations use the same parameter name, it works fine. Because the parameters are named differently the check in RoutingHandler:128 doesn't skip registration with allMethodsMatcher as it would otherwise.
