The Weld EE embededd container would deserve complete revision. Nobody has touched the code for quite a long time. The maven profiles for Weld versions have really old versions and are bit confusing. The Weld 3 version is slowly approaching and could be included (probably in separate branch).

Currently I encountered problem with bean discovery mode. It's not possible to test with ANNOTATED mode because WeldEEMockContainer deploys always with flag "merge=true" which results in bean archive with mode ALL. I guess there will be more similar issues like this.
