[jboss-jira] [JBoss JIRA] (WFLY-11601) Weld vs Undertow bootstrap: Race condition

Weld vs Undertow bootstrap: Race condition ------------------------------------------ Key: WFLY-11601 URL: https://issues.jboss.org/browse/WFLY-11601 Project: WildFly Issue Type: Bug Components: CDI / Weld, Web (Undertow) Affects Versions: 15.0.1.Final Reporter: Stefan Gr Assignee: Matěj Novotný Priority: Major Attachments: TestApp.zip, TestLib.zip, changes.diff, deploy-failed.txt, deploy-mixed-success.txt, deploy-success.txt, test-app-1.0.0.war, weld-core-impl-3.0.5.Final.jar, weld-core-impl-3.0.5.Final.jar 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=1368...]. 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
