Mule 使用Esper和Twitter进行复杂的事件处理会给twitter4j.internal.org.json.JSONException：JSONArray文本必须以'；['；

您好，我正在尝试…中的示例，但它给出了以下异常。原因是：

twitter4j.internal.org.json.JSONException:JSONArray文本必须以 在1处使用“[”字符[第2行]在 twitter4j.internal.org.json.JSONTokener.syntaxError（JSONTokener.java:335） 位于twitter4j.internal.org.json.JSONArray.（JSONArray.java:107） twitter4j.internal.http.HttpResponse.asJSONArray（HttpResponse.java:185） …还有54个

任何人都试过同样的例子，或者任何人都有解决办法。

谢谢。

在使用回家时间表操作时，twitter连接器似乎出现了某种问题（我刚刚申请了jira）

我已经成功地用Esper连接器做了一个简单的mule应用程序来测试它，它工作正常。请告诉我这是否有帮助（代码如下）
