@Startup, @WebListener and (@Observes @Initialized(ApplicationScoped.class) are triggered before some components has started ---------------------------------------------------------------------------------------------------------------------------- Key: WFLY-10261 URL: https://issues.jboss.org/browse/WFLY-10261 Project: WildFly Issue Type: Bug Components: CDI / Weld Affects Versions: 12.0.0.Final Reporter: Daniel Fb Assignee: Brian Stansberry Priority: Major We are migrating our applications from Wildfly 10 to Wildfly 12 and sometimes Wildfly 12 trigger {{@Startup (with @PostContruct)}} or {{@WebListener}} or {{(@Observes @Initialized(ApplicationScoped.class)}} before some components has started. Ex: - At these moments we can't inject remote EJBs (simple {{new InitialContext().lookup(jndi)}}) - Sometimes these {{@Observes}} is fired with null parameter {code} public void observesContext(@Observes @Initialized(ApplicationScoped.class) ServletContext context){ this.context = context; } {code} *These behavior olny occurs when the server is starting with the application deployed*. When the application is deployed after the server is up and running, all goes fine a work.
