When I call history.getBar(...) with a custom period, the method returns null.
IBar bar = history.getBar(instrument, Period.createCustomPeriod(Unit.Hour, 12), offerSide, shift);

the history.getBars(...) method works just fine with custom periods:
List<IBar> bars = history.getBars(instrument, Period.createCustomPeriod(Unit.Hour, 12), offerSide, Filter.ALL_FLATS, 10, history.getStartTimeOfCurrentBar(instrument, period), 0);

You have to subscribe to this period in onStart method

import com.dukascopy.api.listener.*;


        context.subscribeToBarsFeed(
            Instrument.EURUSD,
            Period.createCustomPeriod(Unit.Hour, 12),
            OfferSide.ASK,
            new IBarFeedListener() {
                    public void onBar(
                        Instrument instrument,
                        Period period,
                        OfferSide offerSide,
                        IBar bar
                    ) {
                       
                    }
            }
        );
