解决Hudson部署的错误

部署hudson到JBoss5.1下，出现severe日志如下：

22:04:16,219 SEVERE [ComputerSet] Failed to instanciate class hudson.node_monito

解决方法：
修改USER_HOME的.hudson\nodeMonitors.xml
（windows下是C:\Users\XXX\.hudson）
添加如下内容：

<hudson.node__monitors.TemporarySpaceMonitor>
<ignored>false</ignored>
</hudson.node__monitors.TemporarySpaceMonitor>
<hudson.node__monitors.DiskSpaceMonitor>
<ignored>false</ignored>
</hudson.node__monitors.DiskSpaceMonitor>

然后重启JBoss。

原因及原理不明 - -！

貌似jdk6才有此功能，又或者是未开通jvm的代码
