Unable to start blueprint container for bundle org.opendaylight.aaa.encrypt-service/0.5.0.Carbon due to unresolved dependencies [Initial app config AaaEncryptServiceConfig]

This has happened in recent BGP scale test (1node) after a reboot (which deleted data, so it should be as if initial boot with featuresBoot).

The symptom visible for Robot was just 401 [0], but the karaf.log [1] contained AAA-132 messages:
2017-05-15 23:42:19,110 | WARN | saction-62-64'}} | DeadlockMonitor | 103 - org.opendaylight.controller.config-manager - 0.6.0.Carbon | ModuleIdentifier

{factoryName='rest-connector-impl', instanceName='rest-connector-default-impl'}

did not finish after 284993 ms

This time, the component never unblocked, and the messages suggest perhaps AAA is the guilty part:
