Problem in Pie3D

[David Osorio]

I have the following error when the value of a pie sector is zero, the code is:

public Pie3DChartDemo1(String title) {

super(title);
DefaultPieDataset data = new DefaultPieDataset();
data.setValue("Java", new Double(43.2));
data.setValue("Visual Basic", new Double(10.0));
data.setValue("C/C++", new Double(17.5));
data.setValue("PHP", new Double(32.5));
data.setValue("Perl", new Double(0.0));
JFreeChart chart = ChartFactory.createPie3DChart("Pie Chart 3D Demo 1", data, true);

chart.setBackgroundPaint(Color.yellow);
Pie3DPlot plot = (Pie3DPlot) chart.getPlot();
plot.setStartAngle(270);
plot.setDirection(Pie3DPlot.CLOCKWISE);
plot.setForegroundAlpha(0.75f);
ChartPanel chartPanel = new ChartPanel(chart);
chartPanel.setPreferredSize(new java.awt.Dimension(500, 270));
setContentPane(chartPanel);
}

the error is:
