Description

As discussed on the list usage of System.exit is not ideal and one suggested alternative is to follow up on the idea to instead perform a 'restart of DocumentNodeStore' - while marking the local instance as 'deactivating' towards discovery-lite-descriptor so that upper layer discovery.oak can properly send a TOPOLOGY_CHANGING to all listeners, so that they immediately stop any topology-dependent activity.
