CDI 1.2 defines bean defining annotations and with beans with these annotations should be injectable. However a bean with StereoType, one of bean defining annotations, is not injectable within implicit bean archive on WildFly.

Attached a simple war project to reproduce this problem. This works on GlassFish 4 but doesn't work on WildFly 8.1.0 nor WildFly 9 master at this time. Making this an explicit bean archive by adding empty beans.xml (or set bean-discovery-mode=all) fixes the problem, the container recognizes the CDI bean correctly.
