             * comes from ConfigServiceFactory when it attempts to validate the local yml and finds that both HSM and
             * LASP are enabled. The LASP spec says in this scenario that "Shutdown will follow the behavior of the
             * ForceDisconnectException response from "New Relic." Not specifically that we should throw ForceDisconnectException.
             * Perhaps we should throw a different, more accurately named exception, that simply has the same behavior
             * as ForceDisconnectException as it will be replaced by a 410 response code in Protocol 17.
