1. Is there a portable way to run some code during application startup? The `@Initialized(ApplicationScoped.class) Object` event is fired during container initialization, which can be during application build, so that's not it. I propose CDI standardizes an `AfterStartup` event (symmetrically to existing `BeforeShutdown`), which is guaranteed to be fired during application startup. I personally find `AfterStartup` and `BeforeShutdown` a lot more natural than `@Initialized(ApplicationScoped.class) Object` and `@Destroyed(ApplicationScoped.class) Object`. (Though to be perfectly honest, `BeforeShutdown` seems misnamed and, since all CDI contexts are invalid at that point in time, also quite useless.)
This is easy to implement in a fully runtime environment, so I took the liberty of adding that to StillDI, even though it isn't part of the extension API.
Is there some reason that the `@Initialized(ApplicationScoped.class) Object` event has to run at build time? Could it just be specified that it happens at runtime?
Currently I think this is the only way to ensure that something runs at startup with CDI so it would be a shame to break things that rely on that.
Matej said it better than I can, but I'll reply anyway :-)
The issue is that the `@Initialized(ApplicationScoped.class) Object` event isn't fired during application startup. It's fired when the application context is initialized. So far, this has always been the same, but fundamentally, it's not.
We seek to enable significant optimizations by potentially moving a lot of CDI startup to build time (including the whole bean discovery, extension processing, and more). This includes initialization of the application context.
