Please cherry-pick:

- sadly, Glassfish and Payara are both not so super-flexible to allow JNDI
  lookups in constructors. You have to either move that code to a @PostConstruct
  annotated method in bean (=controller) classes or do it on-demand.
- @PostConstruct, @Observes and so on are not processed outside beans, next
  "limitation" (or not wanted/intended/possible?).
