Issue

When fireAllRules is executed with the AgendaFilter as an argument, for example, like this:

int count = ksession.fireAllRules(new AgendaFilter()
            {
                @Override
                public boolean accept(Activation activation)
                {
                    boolean isAccept = activation.getRule().getName().equals("DG1UncontrolledReset"); 
                    if (isAccept) {
                        return true;
                    }
                    return false;
                }
            });

Following exception can be observed in the logs:
