Тайм-аут сеанса не работает с веб-сокетами

Question

У меня развернуто веб-приложение на glassfish, где у меня есть тайм-аут для сеанса в web.xml:

<session-config>
    <session-timeout>
        1
    </session-timeout>
</session-config>

Это работало нормально, пока я не добавил WebSockets

Внешний интерфейс:

var webSocket = new WebSocket('#{authenticationJSFBean.webSocketURL}');
webSocket.onmessage = function(message){
    switch(message.data) {
        case 'sendRegistrationRequest':
            updateNewRegistrationRequestCount();
            break;
        case 'sendStageRequest':
            updateSourceAndTargetParticipatingCompaniesDataTables();
            break;
};

Backend:

@ServerEndpoint("/websocket/{login}")
public class WebSocketEndpoint {
    private static final Set<Session> sessions = new CopyOnWriteArraySet<>();
    private static final Logger LOG = LogManager.getLogger(WebSocketEndpoint.class);

    @OnOpen
    public void onOpen(@PathParam("login") String login, Session peer) {
        sessions.add(peer);
    }

    @OnClose
    public void onClose(Session peer) {
        if(sessions.contains(peer)) {
            sessions.remove(peer);
        }
    }

    public static void sendMessage(String message) {
        for(Session session : sessions) {
            RemoteEndpoint.Basic endpoint = session.getBasicRemote();
            try {
                endpoint.sendText(message);
            } catch(IOException ioe) {
                LOG.warn("Unable to send message to session\n Message:" + ioe.getMessage());
            }
        }
    }
}

После того, как я добавил это, тайм-аут сеанса перестал работать.Я попытался установить тайм-аут в сеансе websocket:

peer.setMaxIdleTimeout(60 * 60 * 1000);

Сначала это выглядело так, как будто это помогает, но во втором или третьем сеансе у меня ошибка:

И тайм-аутперестает работать снова полностьюКак это исправить?
