**今天在linux上部署dubbo-admin-2.5.4，一直报错：**

ERROR context.ContextLoader - Context initialization failed

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][https_github.com_alibaba_dubbo_issues_50]

重新安装了jdk 1.7后，问题解决。
