> we are currently doing {{ try { Class.forName("...ApplicationScoped") } }} which is 
> (1) pretty hackish (2) won't work in Maven because maven's ClassPath is not the same of the target application
> We should rather use a config param or any better way to detect if we're going to use DI. Currently we have added a config param + "auto detect" using the technique above (in maven only the config param works) but auto-detect should be better.
> Besides ApplicationScoped only work for CDI, while JSR-330 @Inject is independent from CDI so using ApplicationScoped as a signal is too limited.
