1-12 - Instances of "Registry Service" have been destroyed

Possible Reason

During the graceful shutdown of Dubbo, unregister by calling destroyAll of AbstractRegistryFactory.

During the process of destroying the unexport of Registryprotocol, the getRegistry of AbstractRegistryFactory will be used to try to obtain the registry that has been destroyed, which leads to the destruction of all instances of the “registry service”.
