Question

我的一个onError处理程序偶尔没有被调用，导致我的应用程序处于一种挥之不去的状态。

这是我的代码

 tokenSubscription = Observable.interval(pluginProperties.getRefreshTokenInterval(), TimeUnit.MILLISECONDS, Schedulers.io())
            .subscribe(x -> {
                    ConversationContextV3 contextV3 = (ConversationContextV3) authenticationContext.getConversationContext();
                    refreshAccessToken(contextV3);
                },
                error -> {
                    logger.error("Exception after retrying refreshing session token, will attempt to reconnect");
                    disconnect();
                }
            );

当调用refreshAccessToken（）时，它有时会引发异常，然后在onError中处理。以下是预期产量。注意最后一行。

我的问题是，有时似乎从未调用过onError，让我得到这样的日志输出：

2017-09-04 20:11:27.750 [RxCachedThreadScheduler-82] DEBUG c.danlind.igz.brokerapi.BrokerLogin - Refreshing access token

我的代码感觉非常直接，我无法理解会导致这个＆＃34;故障的问题＆＃34;？有任何想法吗？使用RxJava 2.10

偶然没有调用onError
