NPE after redeploy in HttpConversationContextImpl ------------------------------------------------- Key: WFLY-2961 URL: https://issues.jboss.org/browse/WFLY-2961 Project: WildFly Issue Type: Bug Security Level: Public(Everyone can see) Components: Web (Undertow) Affects Versions: 8.0.0.CR1 Environment: windows. firefox Reporter: Leos Literak Assignee: Stuart Douglas Priority: Minor It occurs to me quite regularly: I have servlet, construct some GET URL and find bug. So I fix it, redeploy my war application and press reload in firefox. But WildFly fails with NPE. If I reload the page again, then it works. 22:21:59,888 ERROR [io.undertow.request] (default I/O-3) Blocking request failed HttpServerExchange{ GET /OAuthLogin/callback/google}: java.lang.NullPointerException at org.jboss.weld.context.http.HttpConversationContextImpl.getRequestAttribute(HttpConversationContextImpl.java:47) at org.jboss.weld.context.http.HttpConversationContextImpl.getRequestAttribute(HttpConversationContextImpl.java:13) at org.jboss.weld.context.AbstractConversationContext.copyConversationIdGeneratorAndConversationsToSession(AbstractConversationContext.java:177) at org.jboss.weld.context.AbstractConversationContext.sessionCreated(AbstractConversationContext.java:185) at org.jboss.weld.servlet.ConversationContextActivator.sessionCreated(ConversationContextActivator.java:187) at org.jboss.weld.servlet.HttpContextLifecycle.sessionCreated(HttpContextLifecycle.java:122) at org.jboss.weld.servlet.WeldInitialListener.sessionCreated(WeldInitialListener.java:107) at io.undertow.servlet.core.ApplicationListeners.sessionCreated(ApplicationListeners.java:256) at io.undertow.servlet.core.SessionListenerBridge.sessionCreated(SessionListenerBridge.java:36) at io.undertow.server.session.SessionListeners.sessionCreated(SessionListeners.java:32) at io.undertow.server.session.InMemorySessionManager.createSession(InMemorySessionManager.java:121) at io.undertow.servlet.spec.ServletContextImpl.getSession(ServletContextImpl.java:677) at io.undertow.servlet.spec.ServletContextImpl.getSession(ServletContextImpl.java:691) at io.undertow.servlet.handlers.SessionRestoringHandler.handleRequest(SessionRestoringHandler.java:110) at io.undertow.server.handlers.PathHandler.handleRequest(PathHandler.java:56) at io.undertow.server.handlers.NameVirtualHostHandler.handleRequest(NameVirtualHostHandler.java:53) at io.undertow.server.handlers.error.SimpleErrorPageHandler.handleRequest(SimpleErrorPageHandler.java:76) at io.undertow.server.handlers.CanonicalPathHandler.handleRequest(CanonicalPathHandler.java:43) at io.undertow.server.handlers.ChannelUpgradeHandler.handleRequest(ChannelUpgradeHandler.java:158) at io.undertow.server.Connectors.executeRootHandler(Connectors.java:164) at io.undertow.server.protocol.http.HttpReadListener.handleEvent(HttpReadListener.java:142) at io.undertow.server.protocol.http.HttpOpenListener.handleEvent(HttpOpenListener.java:69) at io.undertow.server.protocol.http.HttpOpenListener.handleEvent(HttpOpenListener.java:38) at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:92) [xnio-api-3.2.0.Beta4.jar:3.2.0.Beta4] at org.xnio.ChannelListeners$10.handleEvent(ChannelListeners.java:291) [xnio-api-3.2.0.Beta4.jar:3.2.0.Beta4] at org.xnio.ChannelListeners$10.handleEvent(ChannelListeners.java:286) [xnio-api-3.2.0.Beta4.jar:3.2.0.Beta4] at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:92) [xnio-api-3.2.0.Beta4.jar:3.2.0.Beta4] at org.xnio.nio.NioTcpServerHandle.handleReady(NioTcpServerHandle.java:53) [xnio-nio-3.2.0.Beta4.jar:3.2.0.Beta4] at org.xnio.nio.WorkerThread.run(WorkerThread.java:531) [xnio-nio-3.2.0.Beta4.jar:3.2.0.Beta4]
