Description

Scenario:
ConfigGroups with host mapping to hosts that no longer exist.
This results in an NPE during lookup from the in-memory Cluster Map.

Host host = clusters.getHost(hostMappingEntity.getHostname());

This is swallowed by the Guice assisted injector leading to partial loading of the data from DB.
