As a more concise example, the code here using a @Startup @Singleton with a @PersistenceContext isn't working for me, it results in the entity manager being null when provided a correct unitName and a proper entity to fetch. I know that example is using OpenJPA and not hibernate, I'm wondering if I'm missing something or if this is a bug.
