我有一个基于maven的mule项目，它原创于mule版本3.2.1。当我更新我的pom.xml以将mule.version从3.2.1更改为3.3.0时，运行我的应用时出现以下异常。
我通过启动`org.mule.MuleServer -config src / main / app / mule-config.xml'在Eclipse中运行应用程序
这与3.2.1一起工作正常。如果我编辑我的pom.xml并将mule.version更改回3.2.1它继续正常运行。但是，我真的需要一些包含在3.3.0中的错误修复。
有什么想法吗？

答案 0 :(得分：1)
确保类路径上的所有Mule工件都是3.3.0版。看来你的版本不匹配，因为mule-core-3.3.0.jar中的SimpleRegistryBootstrap第169行被注释掉了。
