Summary: XYShapeRenderer findRangeBounds NullPointerException

Initial Comment:
In this piece of code:
 public Range findRangeBounds(XYDataset dataset) {
        if (dataset != null) {
            Range r = DatasetUtilities.findRangeBounds(dataset, false);
            double offset = 0; // TODO getSeriesShape(n).getBounds().height / 2;
            return new Range(r.getLowerBound() + offset, r.getUpperBound()
                    + offset);
        }
the Range r may be "null" depending on the dataset, which results in a NullPointerException

Message:
This happens, when dataset contains only elements which are null
