When I read 5.6.1 the only requirement I see is that it has to be a dependent scoped bean. Note when I ask this I'm asking from the spec perspective, its a different problem if there's some issues with implementations following suite (I would imagine there needs to be some shared global registry of dependent scoped beans for this to work). > Sound the only clean impl. Any other is not symmetric and potentially lead to "oops this time it didnt work". I also not seeing any use case limitation with that so think it is the same solution I'm not sure I follow or if this isn't an answer to "Does the spec require destroy() to be called only on instances that it created?" ? Anyways I did look a bit closer and it seems that Martin's statement is consistent with how OWB works, https://github.com/apache/openwebbeans/blob/trunk/webbeans-impl/src/main/... so I wonder if there's a part of the spec I'm missing, or if there was some offline agreement on how to understand it.

I'm thinking more now that it belongs as a reword of 5.6.1 to clarify how to use destroy() on dependent beans, rather than where I put it. I think realistically we have all of the tools needed to manage the lifecycle of these classes, just need to clarify them for people to use. > > John > > _______________________________________________ > cdi-dev mailing list > cdi-dev(a)lists.jboss.org <mailto:cdi-dev@lists.jboss.org> > https://lists.jboss.org/mailman/listinfo/cdi-dev > > Note that for all code provided on this list, the provider licenses the code under the Apache License, Version 2 (http://www.apache.org/licenses/LICENSE-2.0.html).
