Hi Romain, now I understand your point and it sounds valid. I can take a deeper look into it this weekend, but feel free to change it by yourself, if you want.

I guess, it is good to know, which extension observes > ProcessAnnotatedType events and which doesn’t. > Yes, please don't disable that cache which helps to startup faster when using extensions with several beans. Point was more: for (method: methods) { if (is container) {} } for (method: methods) { if (!is container) {} } versus for (method: filter(methods)) { if (!is container) { } else { define(); } } Know it is only #extensions x #methods so likely not crazy but sounds more natural to prepare the runtime in one pass for this no? Concretely it would be something like https://gist.github.com/rmannibucau/c0e9f4020c01ddb9465cad373ccbe1b6 or https://gist.github.com/rmannibucau/b0cff6375af78d3702b5a2c7b8a6a99c if you want to bypass container event test for "not extension" instances (can save a few tests). Concretely your fix ensures that any extension can catch a container lifecycle event issued of another observer definition which is good but keeps the issue that you can still miss event from another extension. Basically it is the same issue between extensions but for normal events. So I think we should just delay GProcessObserverMethod event = new GProcessObserverMethod(webBeansContext, annotatedMethod, observer); webBeansContext.getBeanManagerImpl().fireEvent(event, true, AnnotationUtil.EMPTY_ANNOTATION_ARRAY); to happen after all observers are defined. So overall I'd be to: 0. we keep the cache during the startup ;) 1. keep the observer definition a single loop 2. move the process observer method event firing after all extensions observers definition if possible (means that worse case some vetoed observer will be executed during this time but it is unlikely and we can't help that anyway, even replaying the missed observers - because not yet there - once added) Hope it makes more sense phrased this way and it is not too late to write a technical mail ;). > > Cheers, > Arne > > OPEN KNOWLEDGE GmbH > Poststraße 1, 26122 Oldenburg > Mobil: +49 151 - 108 22 942 > Tel: +49 441 - 4082-154 > Fax: +49 441 - 4082-111 > arne.limb...@openknowledge.de<mailto:arne.limb...@openknowledge.de> > www.openknowledge.de<<http://www.openknowledge.de%3c> > https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.openknowledge.de%2F&data=04%7C01%7C%7C3004d8758be44c8678c008d93bcc1e23%7C48837bc476f9481d8a76bd7b60b43dec%7C0%7C0%7C637606570139932909%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=9vRVYZVZ%2Feqk%2BvFxU5COofNvgs8U0AxtxRqwVEwqXHA%3D&reserved=0 > > > Registergericht: Amtsgericht Oldenburg, HRB 4670 > Geschäftsführer: Lars Röwekamp, Jens Schumann > > Treffen Sie uns auf kommenden Konferenzen und Workshops: > Zu unseren Events< > https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.openknowledge.de%2Fevent%2F&data=04%7C01%7C%7C3004d8758be44c8678c008d93bcc1e23%7C48837bc476f9481d8a76bd7b60b43dec%7C0%7C0%7C637606570139932909%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=8tjmukdm1NxhXQMkn4VnESiBI216kXvh%2Fjb7%2FFYI0kE%3D&reserved=0 > > > > Von: Romain Manni-Bucau <rmannibu...@gmail.com> > Datum: Montag, 11.
