今天在linux上部署dubbo-admin-2.5.4，一直报错：
ERROR context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'uriBrokerService': Cannot create inner bean '(inner bean)' of type [com.alibaba.citrus.service.uribroker.impl.URIBrokerServiceImpl$URIBrokerInfo] while setting bean property 'brokers' with key [0]; nested excepti

仔细对比了一下部署成功的环境，发现配置没有什么不同。于是重新下载了一个部署包，也在自己的电脑上安装了一次，还是报同样的错误。
反编译dubbo的代码看了一下，发现getter和setter方法确实不是很符合规范：
折腾了半天，终于在网上找到遇到同样问题的帖子，见https://github.com/alibaba/dubbo/issues/50
重新安装了jdk 1.7后，问题解决。
