        this.nativeEntityManagerFactoryFuture = bootstrapExecutor.submit(this::buildNativeEntityManagerFactory);
    } else {
        this.nativeEntityManagerFactory = buildNativeEntityManagerFactory();
    }

    // Wrap the EntityManagerFactory in a factory implementing all its interfaces.
    // This allows interception of createEntityManager methods to return an
    // application-managed EntityManager proxy that automatically joins
    // existing transactions.
    this.entityManagerFactory = createEntityManagerFactoryProxy(this.nativeEntityManagerFactory);
}
