EJB client 4 is unable to discover EJB after WildFly crash during previous call and reboot ------------------------------------------------------------------------------------------ Key: WFLY-11664 URL: https://issues.jboss.org/browse/WFLY-11664 Project: WildFly Issue Type: Bug Components: EJB, Remoting Affects Versions: 14.0.0.Final, 15.0.0.Final Reporter: Ivan Straka Assignee: Flavia Rainone Priority: Blocker Attachments: reproducer.zip Issue is not valid for 7.2.0.CD12 (upstream client: 12.0.0.Final) therefore we consider this as a blocker. Lets have two WildFly servers and same EJB on both. They have nothing to do with each other. And the client app that call beans on them. *Scenario* # Client invokes _hello_ method on the first server which crash during the call. Exception is consumed. # Client calls successfully _hello_ method on the second one. # Now, the first server is started again and then the client (same thread) try to call _hello_ on the first one. The call should be successful but the client is unable to discover bean. {code:java}Exception in thread "main" java.lang.RuntimeException: javax.ejb.NoSuchEJBException: EJBCLIENT000079: Unable to discover destination for request for EJB StatelessEJBLocator for "/server-1/HelloBean", view is interface ejb.HelloBeanRemote, affinity is None at client.Client.call(Client.java:41) at client.Client.main(Client.java:21) Caused by: javax.ejb.NoSuchEJBException: EJBCLIENT000079: Unable to discover destination for request for EJB StatelessEJBLocator for "/server-1/HelloBean", view is interface ejb.HelloBeanRemote, affinity is None at org.jboss.ejb.client.EJBClientInvocationContext.getResult(EJBClientInvocationContext.java:592) at org.jboss.ejb.client.EJBClientInvocationContext.getResult(EJBClientInvocationContext.java:528) at org.jboss.ejb.protocol.remote.RemotingEJBClientInterceptor.handleInvocationResult(RemotingEJBClientInterceptor.java:56) at org.jboss.ejb.client.EJBClientInvocationContext.getResult(EJBClientInvocationContext.java:594) at org.jboss.ejb.client.EJBClientInvocationContext.getResult(EJBClientInvocationContext.java:528) at org.jboss.ejb.client.TransactionPostDiscoveryInterceptor.handleInvocationResult(TransactionPostDiscoveryInterceptor.java:133) at org.jboss.ejb.client.EJBClientInvocationContext.getResult(EJBClientInvocationContext.java:594) at org.jboss.ejb.client.EJBClientInvocationContext.getResult(EJBClientInvocationContext.java:528) at org.jboss.ejb.client.DiscoveryEJBClientInterceptor.handleInvocationResult(DiscoveryEJBClientInterceptor.java:115) at org.jboss.ejb.client.EJBClientInvocationContext.getResult(EJBClientInvocationContext.java:594) at org.jboss.ejb.client.EJBClientInvocationContext.getResult(EJBClientInvocationContext.java:528) at org.jboss.ejb.client.NamingEJBClientInterceptor.handleInvocationResult(NamingEJBClientInterceptor.java:79) at org.jboss.ejb.client.EJBClientInvocationContext.getResult(EJBClientInvocationContext.java:594) at org.jboss.ejb.client.EJBClientInvocationContext.getResult(EJBClientInvocationContext.java:528) at org.jboss.ejb.client.TransactionInterceptor.handleInvocationResult(TransactionInterceptor.java:172) at org.jboss.ejb.client.EJBClientInvocationContext.getResult(EJBClientInvocationContext.java:594) at org.jboss.ejb.client.EJBClientInvocationContext.getResult(EJBClientInvocationContext.java:528) at org.jboss.ejb.client.EJBClientInvocationContext.awaitResponse(EJBClientInvocationContext.java:938) at org.jboss.ejb.client.EJBInvocationHandler.invoke(EJBInvocationHandler.java:177) at org.jboss.ejb.client.EJBInvocationHandler.invoke(EJBInvocationHandler.java:112) at com.sun.proxy.$Proxy0.hello(Unknown Source) at client.Client.call(Client.java:35) ... 1 more {code} I hit this issue with 15.0.0.Final, 14.0.0.Final but not with 12.0.0.Final. If client try to invoke _hello_ on the first server before it reboots (exception is consumed), there is no problem after. *Client side* {code:java} public static void main(String[] args) throws Exception { call("server-2", true); call("server-1", true); for (int i = 30; i > 0; i--) { System.out.println(i); Thread.sleep(1000); } call("server-1", false); } public static Properties getCtxProperties() { Properties props = new Properties(); props.put(Context.INITIAL_CONTEXT_FACTORY, "org.wildfly.naming.client.WildFlyInitialContextFactory"); return props; } public static void call(String container, boolean exceptedFailure) { try { InitialContext ctx = new InitialContext(getCtxProperties()); String lookupName = "ejb:/" + container + "/HelloBean!ejb.HelloBeanRemote"; HelloBeanRemote bean = (HelloBeanRemote) ctx.lookup(lookupName); System.out.println(bean.hello()); } catch (Exception e) { if (exceptedFailure) { System.out.println("EXPECTED FAILURE"); e.printStackTrace(); } else { throw new RuntimeException(e); } } } {code} *Server side* {code:java} @Stateless @Remote(HelloBeanRemote.class) public class HelloBean { private static Logger log = Logger.getLogger(HelloBean.class); public String hello() throws RemoteException { log.info("hello called with message"); return "Hello there"; } } {code}
