[jboss-user] [JBoss Seam] - java.lang.NoClassDefFoundError: org.drools.WorkingMemory and

Hello 

After 20 minutes of inactivity (I guess, session is being serialized after that), JBoss throws the following exception to console. 

The application is quite simple Seam one, containng one session-scoped component. No Drools are used explicitly, no jBPM. The only specific feature is Seam Remoting , but error appears even when no Remoting calls were made. 

Any idea what may cause that ? 

Thanks.
