And the logs were showing below details about circular reference:

2024-02-16 23:00:59.572 ERROR 833552 --- [    Test worker] o.s.b.d.LoggingFailureAnalysisReporter   :

APPLICATION FAILED TO START
***************************

Description:

The dependencies of some of the beans in the application context form a cycle:

┌─────┐
|  redisOrcaQueueConfiguration
↑     ↓
|  taskResolver defined in class path resource [com/netflix/spinnaker/orca/config/OrcaConfiguration.class]
↑     ↓
|  canaryJudgeTask defined in URL [jar:file:/kayenta/kayenta-core/build/libs/kayenta-core.jar!/com/netflix/kayenta/canary/orca/CanaryJudgeTask.class]
↑     ↓
|  executionMapper defined in URL [jar:file:/kayenta/kayenta-core/build/libs/kayenta-core.jar!/com/netflix/kayenta/canary/ExecutionMapper.class]
↑     ↓
|  executionLauncher defined in URL [jar:file:/.m2/repository/io/spinnaker/orca/orca-core/sc202108-sb2615-SNAPSHOT/orca-core-sc202108-sb2615-SNAPSHOT.jar!/com/netflix/spinnaker/orca/pipeline/ExecutionLauncher.class]
↑     ↓
|  queueExecutionRunner defined in URL [jar:file:/.m2/repository/io/spinnaker/orca/orca-queue/sc202108-sb2615-SNAPSHOT/orca-queue-sc202108-sb2615-SNAPSHOT.jar!/com/netflix/spinnaker/orca/q/QueueExecutionRunner.class]
└─────┘

Action:

Relying upon circular references is discouraged and they are prohibited by default. Update your application to remove the dependency cycle between beans. As a last resort, it may be possible to break the cycle automatically by setting spring.main.allow-circular-references to true.

```
Similar errors were reported for CanaryJudgeTask, CompareJudgeResultsTask, MetricSetMixerServiceTask, MonitorCanaryTask and RunCanaryTask classes, until fixed for each one of them.
In order to fix the issue, deferred the initialization by using @lazy annotation for above mentioned classes.
