运行JGraphX Hello World示例时的错误消息

Question

当我从JGraphX包中运行HelloWorld.java示例并通过拖放移动单元格时，收到以下错误消息。

java.io.IOException：数据转换失败：不是图像格式，位于sun.awt.DataTransfer.DataTransfer.TranslateTransferable（DataTransfer.java:1293)（位于sun.lwawt.macosx.cdataTransfer.TranslateTransferable（DataTransfer.java:131)（位于sun.awt.DataTransfer.DataTransfer.DataTransfer.DataTransfer.DataTransfer.DataTransfer.DataTransfer.DataTransfer.DataTransfer.DataTransfer.$6)。Curity.ProtectionDomain$1.DoIntersectionPrivilege（ProtectionDomain.java:76)在java.awt.EventQueue.DispatchEvent（EventQueue.java:673)在java.awt.EventDispatchThread.PumpeVentsForFilters（EventDispatchThread.PumpeVentsForFilter（EventDispatchThread.java:244)在java.awt.EventDispatchThread.PumpeVentsForHierarchy（

我正在使用Eclipse Juno和Java SE7 for Mac。我不懂，也找不到什么解决的办法。我真的陷入绝望。请帮帮我.

提前谢谢你。

更新：helloworld.java的代码

public class HelloWorld extends JFrame
{
    public HelloWorld()
    {
        super("Hello, World!");

        mxGraph graph = new mxGraph();
        Object parent = graph.getDefaultParent();

        graph.getModel().beginUpdate();
        try
        {
            Object v1 = graph.insertVertex(parent, null, "Hello", 20, 20, 80, 30);
            Object v2 = graph.insertVertex(parent, null, "World!", 240, 150, 80, 30);
            graph.insertEdge(parent, null, "Edge", v1, v2);
        }
        finally
        {
            graph.getModel().endUpdate();
        }

        mxGraphComponent graphComponent = new mxGraphComponent(graph);
        getContentPane().add(graphComponent);
    }

    public static void main(String[] args)
    {
        HelloWorld frame = new HelloWorld();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(400, 320);
        frame.setVisible(true);
    }
}

您可以通过将静态字段enableImageSupport设置为false来解决此问题。如下所示:com.mxgraph.swing.util.mxgraphransferable.enableImageSupport=false；
