We extended Weld's API for Java SE in the recent 3.0.0.Alpha8 release. The main feature is a new builder for programmatic configuration of managed classes, packages, enabled interceptors and others. This could serve as a draft for the bootstrap API to be added to CDI. See the release blog post for more details: http://weld.cdi-spec.org/news/2015/04/21/weld-300Alpha8/ Jozef
