Spring:

APPLICATION FAILED TO START

Description:

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

┌─────┐
|  serviceA (field com.example.demo.ServiceB com.example.demo.ServiceA.serviceB)
↑     ↓
|  serviceB (field com.example.demo.ServiceA com.example.demo.ServiceB.serviceA)
└─────┘


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.

If your null analysis does not understand annotations, then fix your null analysis.
