        boolean hasMaxActiveFaults()
         The maximum number of faults that can be active at a single time via the configured fault

         route). If not specified, defaults to unlimited. This setting can be overridden via
         ``runtime <config_http_filters_fault_injection_runtime>`` and any faults that are not injected
         due to overflow will be indicated via the ``faults_overflow
