我们一直使用YAJSW version beta-12.05安装WSO2CEP为 Windows 服务。它已经工作了一次，直到我们重新启动服务器，它已经无法启动并报告如下错误日志。

但是，如果我们只是通过 bin 文件夹中的 wso2server.bat 启动 WSO2CEP，它就可以工作。而且我还尝试将整个 YAJSW 文件夹复制到另一台服务器并安装服务，它也可以工作。
WSO2CEP 和 YAJSW 似乎都可以正常工作，但无法在特定服务器上作为服务启动。
服务器具体如下：
OS : Windows 7/6.1/amd64
JVM : Oracle Corporation/1.8.0_74/C:\Program Files\Java\jdk1.8.0_74\jre/64
