[Hippo-cms7-user] Occasional NoClassDefFoundError in Tomcat 6.0.2

Hi there,

Sometimes I get the exception below when starting the CMS (currently
2.09.05) in Tomcat 6.0.2 with Java version 1.6.0_14. A restart of Tomcat
solves the problem. Does  anybody have any idea what is the cause?

Thanks,
Dennis
