Weld & Asynchronous servlets on JBoss 6.0 M2 -------------------------------------------- Key: JBAS-8294 URL: https://issues.jboss.org/browse/JBAS-8294 Project: JBoss Application Server Issue Type: Bug Components: Weld/CDI Reporter: William Draï Fix For: 6.0.0.Final Weld seems to break asynchronous servlets 3 (new in JBossWeb). I think it's because the Weld/JBoss integration maps all requests to the ConversationPropagationFilter that is not marked async-supported . Strangely this filter is not applied to servlets implementing HttpEventServlet but it's probably a normal JBossWeb behaviour. Besides that I'm not in a JSF environment so I don't need this conversation propagation, is there any way to disable this filter ?
