和字节码生成相关，上面的信息还不方便排查是什么原因引起。
PS: http://stackoverflow.com/questions/20038523/what-causes-this-error-java-lang-verifyerror-inconsistent-stack-height-2-1

一个简单解决方法是，把proxy改成用jdk的实现：

javassist.jar 字节码生成。
如果<dubbo:provider proxy="jdk" />或<dubbo:consumer proxy="jdk" />，以及<dubbo:application compiler="jdk" />，则不需要。

详见 User Guide http://dubbo.io/User+Guide-zh.htm

谢谢

我调整了配置，然后我的jdk是1.7的，dubbo是1.6的，有冲突就没用，我排查了这个接口的所有方法， 我发现在Impl里的方法必须带入参，加入了参数，就没有这个问题了，完美启动

Dubbo：2.5.3，遇到类似错误，Debug发现是某个Service与其实现类不一致，引用老的JAR包，导致老的实现类未实现当前接口的方法引起报错。对于这个问题，Dubbo输出的错误信息还不够完整，没法一眼看出问题在哪里。

我也遇到这个问题了,2.5.3的版本,请问service和实现类不一致是什么意思?

[edwardlee03]

XxxService为Dubbo服务，XxxServiceImpl是XxxService的实现类。在本地开发某个版本，对XxxService声明的接口做了调整，前后方法签名不一样。服务提供方的其它项目模块引用老的JAR版本(xxx-provider-1.0.2-SNAPSHOT -> xxx-api-1.0.1，正确：xxx-provider-1.0.2-SNAPSHOT -> xxx-api-1.0.2-SNAPSHOT)，引起两边不一致。这样解释说明白了没？ @programmeres
