Android 当服务器拒绝连接时，带缓存的Websocket排队会产生崩溃

设置

导致此异常不可能被捕获：

File cacheDirectory = new File(app.getCacheDir(), "network_cache");
        if (!cacheDirectory.exists()) {
            cacheDirectory.mkdir();
        }
        Cache cache = new Cache(cacheDirectory, CACHE_MAX_SIZE);
        OkHttpClient okHttpClient = new OkHttpClient();
        okHttpClient.networkInterceptors().add(new StethoInterceptor());
        okHttpClient.setCache(cache);

这发生在OKHTTP2.5和OKHTTPWS2.5中。使用OKHTTP2.4和OKHTTPWS2.4，我们得到了一个没有stacktrace的崩溃

删除缓存可修复该问题
