[JBoss JIRA] (CDI-519) Instance.destroy() cannot be used for dependent bean instances not created by the same Instance object
by Martin Kouba (JIRA)
[ https://issues.jboss.org/browse/CDI-519?page=com.atlassian.jira.plugin.sy... ]
Martin Kouba commented on CDI-519:
----------------------------------
bq. 2. to explicitly state that Instance<T> can be used to destroy any dependent scoped bean instance of T.
I'm not sure this is doable. A dependent bean instance doesn't know the object it depends on. That's what {{CreationalContext}} is for.
bq. In your example if we go for 1, there will be no solution to destroy the instance you requested thru CDI.
Well, it is. But it's not so easy to implement and also not 100% reliable (see WELD-1917 for more info how this is solved in Weld 2.2.11+). Moreover, it's not clear in the spec - e.g. the {{CDI.current()}} contract does not state anything about the identity of the CDI instance you get and whether it should be possible to use it to destroy any bean instance.

Re: [cdi-dev] F2F more information regarding the location
by Werner Keil
Hi Antoine/all,
So the F2F is only 2 days now, or what's the "non community day"? Must be
RH-internal I suppose. I have to see, if Saturday is worth it, also based
on agenda items being fleshed out (and travel or accomodation costs)
So far Mark who referred to last year's F2F doesn't seem to come from "a
bit further East" than myself it seems?
While I did not see him as speaker for ApacheCon in Budapest, he probably
goes there since it isn't as far, so some, especially EG Member and fellow
speaker Anatole should be in Budapest less than a week later, too.

Re: [cdi-dev] F2F more information regarding the location
by Werner Keil
Antonio,
Thanks for the update. I am waiting for the exact agenda, but I would not
be able to join before Sat. If some leave on Sat or it is fairly short that
day, I may not take the ride. If I do, I probably won't be in Paris yet
before later in the evening, depending on train connections from Bern.

Re: [cdi-dev] Time to start working on CDI lite
by Werner Keil
>Forget about all the Android area for now. In android there are not even
Annotations afaik. And Android is NOT Java. The runtime and all the
bytecode stuff we do here wont work that easily. So we would get rid of
TONS of neat stuff a >JavaSE app most of the times would LOVE to have.
This was still from Square's time, but shows at least @Qualifier or
@Module annotations (aside from the obvious @Override) so it looks like
some annotations do work for Android
https://github.com/square/dagger/tree/master/examples/android-simple
Can't speak for JBoss or Red Hat here, but at least their AeroGear native
libraries for Android https://aerogear.org/android/ speak a rather clear
language, and should any of CDI lite be usable to both Java SE and Android
I am sure, AeroGear would happily offer it there;-)

Time to start working on CDI lite
by Antoine Sabot-Durand
Hi guys,
CDI lite is one of the big feature we are expected to deliver for version
2.0. I think it's time to start discussing about its design.
The big picture is to provide a consistent subset of CDI that could be
implemented like Dagger is (code generated with process annotation). This
would allow using CDI in constrained environment like mobile or embedded
devices.
IMO CDI lite should be targeted to Java SE (I don't think it would make
sense for Java EE). So, from a specification perspective, we''l probably
have to split core part in 2 and se part as well (gosh).
I'm not sure regarding API. today they only weight 72 KB, so creating a
subset only for the sake of the weight doesn't make sense. the only reason
would be to have something clearer for the end user. but that could be
tricky.
