I've made a test and I've got the same behavior. On the Cache injection point I've got a warning saying that "no bean is eligible for injection".
Which classes/annotations are missing?
I've just seen that I've missed to mention that @ConfigureCache annotation is only available since Infinispan 5.1.0.ALPHA1 (this annotation was previously named @Infinispan in 5.0/5.0.1).
