6.0BIM启动控制台报java.lang.UnsupportedClassVersionError错。

新安装的6.0服务器和bos，打了最新的补丁，导了方案，启动bim时客户端无反应，看bim控制台发现有如下异常：

java.lang.UnsupportedClassVersionError: com/kingdee/eas/perflog/client/PerfLogInit (Unsupported major.minor version 49.0)

解决方法如下：

打开【解决方案/runtime/client/deploy/client/config.xml】文件，将其中的

<attribute key="10" value="com.kingdee.eas.perflog.client.PerfLogInit"/>

删掉或注释掉保存，然后重启bim即可。
