[JBoss JIRA] (CDI-625) When exactly are events with @Initialized(X.class) and @Destroyed(X.class) qualifiers fired

by Martin Kouba (JIRA)

[ https://issues.jboss.org/browse/CDI-625?page=com.atlassian.jira.plugin.sy... ] Martin Kouba commented on CDI-625: ---------------------------------- {{@AfterDestroyed}} is the new {{@Destroyed}} - just to have consistent names. And if you ask for purpose - it's just backward compatibility. We cannot change the behavior of {{@Destroyed}} and we cannot remove the annotation either.

[JBoss JIRA] (CDI-634) Clarify contextual reference validity to a bean with a normal scope in Java SE

Proposed times for video chat on context management APIs

by John Ament

All, In talking with Antoine this morning, the proposal is going to be to keep next Tuesday's meeting. Instead of hosting on IRC, we'll do a google hangout. We need at least myself, Martin and Mark on the video (Antoine would like to be there as well [😉] ). So does that time work for everyone? If not, do any other times on Tuesday work?

[JBoss JIRA] (CDI-420) add a bean-discovery-mode 'scoped'

by John Ament (JIRA)

[ https://issues.jboss.org/browse/CDI-420?page=com.atlassian.jira.plugin.sy... ] John Ament commented on CDI-420: -------------------------------- Don't forget to raise a PR with the spec changes.

Effectively doing the processing but not make them @Dependent automatically if there is no scope annotation at the end of the PAT processing. > I'm not yet 100% sure how important this distinction is in practice. Just writing this up to not forget about the idea... -- This message was sent by Atlassian JIRA (v6.4.11#64026)
