The problem is critical, because after this exception application stops to function : button that invokes component method simply does not do that anymore. 
Please post at least any thoughts if not solutions. Does any library use these "Drools" implicitly ? Seam core, Seam remoting, JBoss EJB3 ? How is it possible that application is looking for org.drools.WorkingMemory class upon passivation ? 
In order to exclude the influence of previously deployed applications, I installed another instance of JBoss from scratch. The same effect. Tried JBoss 4.0.5 and 4.2.1. Seam version is 1.2.1GA.
