> With the following conditions:
> - A persisted ksession
> - RETEOO engine
> - ksession is disposed while a timer is activated
> - ksession is loaded with a new kbase which doesn't have a rule which associated with the timer
> ActivationTimerInputMarshaller.deserialize() throws a NullPointerException so failed to load the ksession.
