For the record, these tests do not work on Weld only by accident. Weld does not treat it as a deployment problem because it's not required by the spec. See also "3.15. Unproxyable bean types":

A bean type must be proxyable if an injection point resolves to a bean:

• that requires a client proxy, or
• that has an associated decorator, or
• that has a bound interceptor.

And there's no injection point which resolves to the YoghurtConstructor.
