| Hi guys, I have retrieved some extra logging from the Bootstrap and BootstrapTracker, see below. We noticed we never got the `beanIdentifierIndexBuilt`-logging and after looking into it we suspect the identifier index gets built for an empty list of beans because WeldStartup only lists SessionScoped and ConversationScoped beans (see `WeldStartup#getBeansForBeanIdentifierIndex`) so the race condition happens in the
if (beans.isEmpty()) { |
index = new BeanIdentifier[0]; |
reverseIndex = Collections.emptyMap(); |
indexHash = 0; |
return; |
}
|
between the setting of the index and the setting of the reverseIndex  Relevant part of the logging:

That UpdateNotifier is part of an @Startup bean. The exception at the end is where the NPE happens. Nowhere in our log do we get the "Bean identifier index built" message, which is consistent with WeldStartup passing an empty list to `BeanIdentifierIndex#build(...)`. |
