Stefan Gr commented on WFLY-11601:
----------------------------------

Sorry, I had some problems building WELD behind the company proxy (some dependencies couldn't be resolved)...

I've just installed your weld version to the WF15 testserver I have and restartet it multiple times using my test application.
I got no errors at all. Even the real world applications seem to work just fine.

> WFLY-9732 / WFLY-10784 moves the completion of WELD from the WeldStartService to WeldStartCompetionService. This causes a race condition with the UndertowDeploymentService which executes the servlet listeners for context-initialized which again fires ApplicationScope-initialized events in CDI.
> You can find more in [WELD-2557|https://issues.jboss.org/browse/WELD-2557?focusedCommentId=13682848&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13682848].
> In short: WeldStartCompletionService and UndertowDeploymentService pushes the logic to the executor service. It may happen, that the logik of undertow runs before the weld completion. Events fired in the servlet listeners won't find all event observers.
> A possible solution would bo to set the WeldStartCompletionService as a dependency of the UndertowDeploymentService
