Android error before plotting data: Invalid Region.Op - only INTERSECT and DIFFERENCE are allowed

Question

I needed to update my application to SDK 28 and errors showed in all activities that call plottings as java.lang.IllegalArgumentException: Invalid Region.Op - only INTERSECT and DIFFERENCE are allowed

All error appoint to follow method:

 @Override
protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);
    this.chart.draw(canvas, chartArea);
}

This app uses org.afree.chart.AFreeChart and the following class is required:

public class GraphView extends View {

private AFreeChart chart;
private RectShape chartArea;
private Handler mHandler;

public GraphView(Context context, AttributeSet attrs) {
    super(context, attrs);
    mHandler = new Handler();
    chartArea = new RectShape();
}

@Override
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
    super.onSizeChanged(w, h, oldw, oldh);
    chartArea.setWidth(w);
    chartArea.setHeight(h);
}

@Override
protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);
    this.chart.draw(canvas, chartArea);
}

public void setChart(AFreeChart chart) {
    this.chart = chart;
}

public void repaint() {
    mHandler.post(new Runnable() {
        public void run() {
            invalidate();
        }
    });
}

}
