EXECUTE: Create two dependent CDI projects: ProjectA and ProjectB. Project A is included in the class path of project B.
EXECUTE: Add Seam REST jars into ProjectA.
EXECUTE: Create the following bean in of ProjectA:

public class TestBean {
    @Inject @RestClient("http://example.com")
    String taskService;
}

FAILURE: There is a problem marker on the injection. It will disappear only if you add Seam REST jars in ProjectB too.
