I have this in my code base:

    private static DeltaValue getUpcomingThresholdCAPDeltaValue
    (BigDecimal aInCurrentValue,CounterInstanceClass aInCounterInstanceClass,
            ProrateInfo aInProrateFactor,REWrapper aInREWrapper)
    {
        List<ThresholdProfileGroupInstance> lThresholdCapInstances =
                EntityCounterUtility.getCounterThresholdCapList
                        (aInCounterInstanceClass);
        TPAResources.debug(logger, "process for getting list of Caps" ,
                " and Thresholds from counter completed.");
        CounterCapThresholdReservation lCounterCapThresholdReservation=new CounterCapThresholdReservation();
        lCounterCapThresholdReservation.setRatingEngineRequest(aInREWrapper.getRatingEngineRequest());
        List<DeltaValue> lOutCapThresholdDeltas = lCounterCapThresholdReservation.getMinTPGDelta
                (lThresholdCapInstances, aInCurrentValue,
                        RatingCallActions.COMMIT, aInProrateFactor,
                        aInCounterInstanceClass.getUsageLimit(),
                        aInCounterInstanceClass.getKindOfUnit(),
                        aInCounterInstanceClass.getMaxOverageCount());
        DeltaValue lOutCapThresholdDelta = lOutCapThresholdDeltas.get(0);
        setHardStopDeltaIfRejectAction(lOutCapThresholdDeltas, lOutCapThresholdDelta);
        checkAndSetSPInRecurrentThresh(aInREWrapper, lOutCapThresholdDeltas);
        TPAResources.debug(logger, "minDelta value of upcoming " ,
                        "threshold and counter current value:",
                lOutCapThresholdDelta);
        return lOutCapThresholdDelta;
    }

Why the HELPER approach is not working ?

Tried explicit casting as

com.nokia.tpapps.ratingcore.engine.impl.ThresholdExecutionUtility.setHardStopDeltaIfRejectAction($lOutCapThresholdDeltas, (com.nokia.tpapps.servicemodel.model.DeltaValue)$lOutCapThresholdDeltas.get(0));

It fails to submit at first place itself.
