Hi,  
are you using the Clover engine supplied with the GUI or some other engine?

Hi,  
I use an other engine but I don’t know in which version.

Hi,  
you are probably using an older version of the engine. I would recommend using the one bundled with the GUI. The other option is turning off tracking in the GUI, in Preferences-\>Clover.ETL-\>Tracking .

Thanks Jaro,  
I solved my problem by updating my classpath file.
