RestartParentResourceHandlerBase.requiresRuntime is not accounting for ProcessType.EMBEDDED_HOST_CONTROLLER in its logic, assuming that ProcessType.HOST_CONTROLLER is the only enum value for an HC. This is wrong and is the cause of WFLY-8923.

There may be other similar problems in the code. All uses of ProcessType.HOST_CONTROLLER should be inspected. Probably a ProcessType.isHostController() method should be added (I believe just returning !isServer()) to help guide coders to use the API of ProcessType and not rely on the enum values.
