Ошибка входа в Spring Cloud Vault при запуске приложения ⇐ JAVA

[Anonymous]

Я использую Spring Cloud Vault с аутентификацией Kubernetes и использую аннотации @VaultPropertySource в своих классах свойств конфигурации, но иногда замечаю это раздражающее и страшное исключение VaultLoginException при запуске приложения. при этом приложение продолжает запускаться и работать.

Мои вопросы:
1- Что это? Является ли это временной проблемой с подключением при запуске, которая быстро исчезает, и именно поэтому приложение может продолжить работу менее чем за секунду?
2. Как изменить поведение, чтобы оно повторяло попытку и ждало еще немного, прежде чем распечатывать эту пугающе вводящую в заблуждение трассировку стека?
