Weld cannot find producer method in library jar

Using Wildfly 8.2.0.Final, which I believe uses Weld 2.2, I've reproduced this issue with 2 simple classes in a Maven multimodule project. One produces a javax.ws.rs.client.Client, another has an injection point for the same. Arquillian deployment fails with WELD-001408: unsatisfied dependencies.
The producer is in a library jar that gets included in the WEB-INF/lib for the consumer. Producer has a beans.xml in the META-INF with discovery-mode=annotation and the consumer has one in WEB-INF with discovery-mode=all.
