[JBoss JIRA] (CDI-494) Clarify that a type variable that resolves to a wildcard is not resolvable

by Antoine Sabot-Durand (JIRA)

[ https://issues.jboss.org/browse/CDI-494?page=com.atlassian.jira.plugin.sy... ] Antoine Sabot-Durand commented on CDI-494: ------------------------------------------ This discussion already occurred on the mailing list: http://cdi-development-mailing-list.1064426.n5.nabble.com/Events-and-Type... And obviously some people changed their mind may times on the topic. I think that if it's doable in the impl, we should clarify in the less strict version (i.e allowing unbounded wildcards) so +1 for PR with JLS compliant rewording. > Clarify that a type variable that resolves to a wildcard is not resolvable > -------------------------------------------------------------------------- > > Key: CDI-494 > URL: https://issues.jboss.org/browse/CDI-494 > Project: CDI Specification Issues > Issue Type: Clarification > Components: Events > Affects Versions: 1.2.Final > Reporter: Jozef Hartinger > Fix For: 2.0 (discussion) > > > This is implicit but I've seen people confused about this several times.

[JBoss JIRA] (CDI-10) Add ability to access a bean instance from a proxy

by Bauke Scholtz (JIRA)

[ https://issues.jboss.org/browse/CDI-10?page=com.atlassian.jira.plugin.sys... ] Bauke Scholtz edited comment on CDI-10 at 3/12/16 3:18 PM: ----------------------------------------------------------- I understand that, but those beans are not part of public API. It's an implementation detail and not supposed to be intercepted/injected/whatever by enduser. Arjan Tijms suggested a potential alternate solution: a producer with a package private qualifier. I will try that sooner or later. Update: it was quite convoluted and inefficient. In the end I went for "plain" protected methods along a disclaimer in javadoc. Nonetheless, ability to unwrap the CDI proxy via native API is still much appreciated :) was (Author: bauke): I understand that, but those beans are not part of public API.

[ https://issues.jboss.org/browse/CDI-10?page=com.atlassian.jira.plugin.sys... ] Mark Struberg commented on CDI-10: ---------------------------------- Have not read through all the comments, but context.get(bean) will only give you the 'Contextual Instance', means the singleton in the context. But that might already be wrapped with an Interceptor/Decorator proxy, so you don't have guaranteed access to the native class neither :/ > Add ability to access a bean instance from a proxy > -------------------------------------------------- > > Key: CDI-10 > URL: https://issues.jboss.org/browse/CDI-10 > Project: CDI Specification Issues > Issue Type: Feature Request > Components: Beans > Affects Versions: 1.0 > Reporter: Stuart Douglas > Fix For: 2.0 (discussion) > > > There are occasions when it would be useful to access a bean instance directly from a proxy.
