Groovy plugin exception

Hi

I have installed groovy plugin as documented on the plugin description page. But I am getting the following in the teamcity server logs. Anyone else had this problem? Is this plugin not compatible with the version of TeamCity which I have (that is what it looks like to me as a beginner user of TeamCity)?
