No because "On Demand" doesn't "On Undemand". :-) If somebody references the bean we deploy it, but we don't undeploy it when it is de-referenced. That is mainly because it would wasted effort if the referencer is just redeloying. For class dependencies the issue is different. You have to redeploy if the class changes or undeploy if the class is removed. It's not difficult, the semantics are just a bit exacting.
