> Following the upgrade to Spring Framework 5 in NIFI-8502, a cluster node can
> fail start due to a null {{ClusterNodeFirewall}} object. The
> {{FileBasedClusterNodeFirewallFactoryBean}} returns null when no
> configuration file exists, which causes ApplicationContext.getBean() to
> return a {{NullBean}} in {{NodeClusterCoordinatorFactoryBean}}.
