             Summary: Websocket onClosed not called on idle timeout
                 Key: WFLY-3490
                 URL: https://issues.jboss.org/browse/WFLY-3490
             Project: WildFly
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Web Sockets
    Affects Versions: 8.1.0.Final
         Environment: Wildfly 8.1.0 Final on Linux (Centos/Fedora)
            Reporter: Emanuele Colombo
            Assignee: Stuart Douglas


When implementing a JSR-356 websocket endpoint I set

{{session.setMaxIdleTimeout(5000);}}

in the *@OnOpen* method. This means that, if no traffic is generated on the websocket in five seconds, the websocket is automatically closed.

Now, if the websocket si correcly closed by the client calling the "close" method in JS, the corrispective *@OnClose* method on the endpoint is called. But if the websocket is closed because of the idle timeout, on the server the *@OnClose* method is not called, and also *@OnError* method isn't called.

I think the correct behaviour should be to call *@OnClose* even when the socket is closed because of the idle timeout, so that the application has the ability to make some cleanup. Also, this is the behaviour I see when deploying in other Java web/application server.

The test code of my endpoint is the following:

{code:title=EchoEndpoint.java|borderStyle=solid}
@ServerEndpoint("/ws/echo")
public class EchoEndpoint {
    
    @OnMessage
    public String onMessage(String message) {
        System.out.println("RECV: " + message);        
        return message;
    }

    @OnOpen
    public void onOpen(Session session) {
        session.setMaxIdleTimeout(5000);
        System.out.println("OPEN");
    }

    @OnClose
    public void onClose() {
        System.out.println("CLOSE");
    }

    @OnError
    public void onError(Throwable t) {
        System.out.println("ERROR");
    }  
}
{code}
