ODL TestTool订阅NETCONF通知后无法接收，日志报找不到顶层模块

问题背景 #

我按照OpenDaylight（ODL）用户指南，使用其提供的TestTool实现NETCONF通知功能，目前仅能完成订阅操作，无法接收通知。参考的流程文档：

• TestTool通知支持文档：OpenDaylight Netconf TestTool Notification Support
• ODL用户指南NETCONF通知接收部分：Receiving NETCONF Device Notifications on a HTTP Client

错误日志 #

分析ODL日志后发现以下错误：

WARN [globalWorkerGroup-3-1] An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception.
java.lang.IllegalArgumentException: Unable to parse notification <notification xmlns="urn:ietf:params:xml:ns:netconf:notification:1.0">
