OK - case cracked, for the most part.
So what was happening was that @PostConstruct on the CDI bean was being called and it was throwing an exception leading to the object the getter was returning to be NULL.
The logging of the exception was being eaten though because the web app uses log4j and for some reason during this point in the deployment lifecycle log4j is not properly initialized. I had a hunch about this and changed the logging over the JUL for this CDI bean et voila I could see the errors in the server.log.
I would love to see a clean way, on a per app basis, of integrating log4j into GF but from what I have read so far there isn't. If anyone can point me to details on how to do this cleanly on a per app basis I am all ears. Bonus points for a clean SLF4J/logback integration on a per app basis (all jars and config files packaged and deployed w/the WAR).
The other interesting thing, and I don't have an explanation for this, is that the break point I had set in the @PostConstruct method of the CDI bean (first line that can't be missed) never gets tripped. I would have expected to see it tripped when the container calls this method but I doesn't.

It is injected all over the place, including in this @Startup @Singleton. As a test I disable the EJB and observed the @PostConstruct method on the CDI bean is called when it is being injected into a ServletContextListener so I don't think that is the case. It feels like it is I think this is EJB/CDI lifecycle related.
