error on running tests

[jnl001]

hi all...

i created a class, Item, and added a few attributes (using 'add field'). created new integration test ('new integration test...'). tried running 'mvn test' and ran into error below. The build stated all tests (9 total) ran with no errors or failures. Taking a look at the error, I didn't think the exception was valid, so i'm posting here...

thanks





Returning eagerly cached instance of singleton bean 'entityManagerFactory' that is not fully initialized yet - a consequence of a circular reference
BeanConfigurerSupport failed to create target bean 'entityManagerFactory' while configuring object of type [org.mycompany.sample.application.roo.domain.Item] (probably due to a circular reference). Proceeding without injection.

Whenever the Roo tests run successfully, you can be assured there is no problem. The tests are very comprehensive and accurately reflect whether the desired persistence operations are working or not.

The circular reference noted below is a known issue to do with Hibernate. What's happening is Hibernate is instantiating all entities as part of its configuration phase. The instantiation of an entity in turn triggers Spring's @Configurable capability to be used, which attempts to dependency inject the entity. The entity in turn has a @PersistenceContext, which requires the injection of an EntityManager into the entity. The EntityManager cannot yet be injected, as Hibernate is still initialising. Spring understands this loop and dutifully logs it for your information, but it's not a problem.
