I'm using spring-data-jpa 3.3.0 with multiple data sources and entity managers and therefore I have multiple @EnableJpaRepositories annotations. I now wanted to change the bootstrap mode to DEFERRED but I get

java.lang.IllegalStateException: Could not register object [org.springframework.data.repository.config.DeferredRepositoryInitializationListener@7aae1170] under bean name 'org.springframework.data.repository.config.DeferredRepositoryInitializationListener': there is already object [org.springframework.data.repository.config.DeferredRepositoryInitializationListener@4ef5dd23] bound

as each time the @EnableJpaRepositories annotation is processed RepositoryConfigurationDelegate tries to register a DeferredRepositoryInitializationListener bean.

Only register DeferredRepositoryInitializationListener once.

Good catch, on it!
