ApplicationReadyEvent fires multiple time while using SpringApplicationBuilder

Using ApplicationListener<ApplicatioReadyEvent> with the usage of SpringApplicationBuilder fires multiple notification to that listener (for every child). Please have a look to that small demonstration: demo.zip

Issue created after stackoverflow question comment: here

Regardless I think we should fix it somehow. If we agree the scope of the application is independent of the structure of the application context, then we should fire it only once and at the appropriate time. Not sure however that everybody share the same concept of “application” (perhaps the builder is used to start several apps in isolation in child context?).

i.e. we already perform ApplicationContextAware injection for ApplicationListener

Doh - I didn’t notice that code. I guess I am ok with not doing auto wiring - agreed that doco is probably enough at this point.

That said, I am sure I would only use this feature when interested with those “early” events and use a @Bean for a “proper” listener.
