Sorry to drag this up again, but this has changed now that
manager.getReference(...) requires a CreationalContext, about which I
know very little. I'll try reading the latest spec soon, but in the
meantime if anyone has any silver bullets please let me know.

I'm currently using this utility method:

    public static <T> T getInstanceByType(BeanManager manager,
Class<T> type, Annotation... bindings) {
        return (T)manager.getReference(
                manager.getBeans(type).iterator().next(), type, null);
    }

Obviously it's that null at the end (where CreationalContext should
be) that's causing the problem.
