in `AbstractRegistryFactory#getRegistry`, if `NacosConnectionManager#createNamingService` throw Exception `IllegalStateException` and set `registry.check = false`，the variable `registry` will return `null`. maybe it can throw an Exception such as `RegistryCreateFailException` instead of return `null`. in `ServiceConfig#doExportUrl` we can catch the Exception `RegistryCreateFailException` and handler the exception by step: 1. unexport the return `exporter`， 2. record the fail registry in `ServiceConfig#doExportUrls` calculate the failure rate, if the rate out of bounds the service may export fail. we can add config `service.checkThreshold` defaine the failure rate. in `MultipleRegistry` the registry url from qs `reference-registry` and `service-registry`, the register and subscribe use the different connection. in `MultipleServiceDiscovery` the registry url from qs `child.*`. register and subscribe to share these connections. should we define Multiple failure behavior here, such as the failure rate of multiple connections. -- This is an automated message from the Apache Git Service.
