我试图用snakeYAML 1.13序列化一个包含哈希图的类，结果得到了一个非常奇怪的stackoverflow：

完整的代码在课堂上也有一些其他的东西，为了简单起见我把它们去掉了

使用的示例代码：

import java.awt.Point;
import java.util.HashMap;
import org.yaml.snakeyaml.Yaml;


class TestClass
{
    public static void main(final String args2[])
    {
        IZSkinFile f = new IZSkinFile();
        HashMap<String,Point> ep = f.getElementPositions();
        ep.put("another unimportant name",new java.awt.Point(10, 10));
        System.out.println(new Yaml().dump(f));
    }
}

class IZSkinFile
{
    public IZSkinFile(String uprogram)
    {
        elementPositions = new HashMap<>();
    }
    public IZSkinFile(){
    elementPositions = new HashMap<>();    
    }//serialisierer....
    // private HashMap<String,String> elementDefinitions;//name>typ (Grafik/text/Schriftart)
    private HashMap<String,Point> elementPositions; //basisposition des elements
    public HashMap<String, Point> getElementPositions()
    {
        return elementPositions;
    }

    public void setElementPositions(HashMap<String, Point> elementPositions)
    {
        this.elementPositions = elementPositions;
    }
}

结果遵循 Stackoverflow（仅显示上下端以节省不必要的行：

发现了一个愚蠢的问题......即使它只有 2 个属性，它也会
以某种方式搞砸。由于该错误使我发疯，因此现在java.awt.Point使用具有 2 个整数的数组进行存储。int[]
