Hi guys, I just push a new version for PR 270 https://github.com/cdi-spec/cdi/pull/270 No more strange inheritance, Builders now use Configurator by composition. I kept the distinction between configurator and builder to have different restriction between both. BeanConfigurator duplicates all methods from BeanAttributesConfigurator, an alternative might be to compose them (BeanConfigurator consumes a BeanAttributesConfigurator) Thanks for your review. This PR is important to decide how we may manage other ticket like new version of SE bootstrap (CDI-568) or interceptor on producer (CDI-580) Antoine
