TextLayer->byte[]->TextLayer报错

1.源代码：

public static void main(String[] args) throws FileNotFoundException {
License license = new License();
String licFileDir = "E:\\mysite\\openproj\\Aspose.PSD-for-Java\\Examples\\src\\main\\resources\\Lic\\Aspose.Total.Product.Family.lic";
license.setLicense(licFileDir);
String dataDir = "E:\\mysite\\openproj\\Aspose.PSD-for-Java\\Examples\\src\\main\\resources\\PSD\\";
String sourceFileName = dataDir + "nvwangJy.psd";
String exportPath = dataDir + "nvwangNewTextUpdateTwoResult.png";
PsdLoadOptions loadOptions = new PsdLoadOptions();
//Try this
//loadOptions.setLoadEffectsResource(true);
PsdImage image =(PsdImage) Image.load(sourceFileName,loadOptions);

for(int i=0; i < image.getLayers().length; i++ )
{
    Layer layer = (Layer) image.getLayers()[i];
    //System.out.println(i + "DisplayName:" + layer.getDisplayName() + "name:" + layer.getName());
    if (i == 11 && image.getLayers()[i] instanceof TextLayer)
    {
        TextLayer textLayer = (TextLayer)image.getLayers()[i];
        System.out.println("this is a textLayer");

        byte[] layerBytes;
        MemoryStream layerMem = new MemoryStream();
        OutputStream dstStream = layerMem.toOutputStream();
        textLayer.save(dstStream, new PsdOptions());
        layerBytes = layerMem.toArray();
        layerMem = new MemoryStream(layerBytes);
        //InputStream inputStream = new ByteArrayInputStream(layerBytes);
        //textLayer =  new Layer(layerMem);
        textLayer = (TextLayer)new Layer(layerMem.toInputStream());

        Point leftTopCoordinate = new Point();
        leftTopCoordinate.setX(textLayer.getLeft());
        leftTopCoordinate.setY(textLayer.getTop());
        textLayer.updateText("靠你就是我\r我的\r你的", leftTopCoordinate, ((TextLayer)textLayer).getFont().getSize(), ((TextLayer)textLayer).getTextColor());
    }
}
    PngOptions options = new PngOptions();
    options.setColorType(PngColorType.TruecolorWithAlpha);

    image.save(exportPath,options);
}

2.源psd文件：
nvwangJy.zip (2.6 MB)

3.实际结果：
image.png (8.6 KB)

4.期望结果：
nvwangNewTextUpdateExpect.jpg (277.6 KB)

PS:希望官方有支持TextLayer、Layer、PsdImage->byte[]->反序列化源对象（源TextLayer、Layer、PsdImage）。和达到LoadPsd源文件的图层操作效果。说白了，Image.load(sourceFileName,loadOptions)出来的图层结果和图层layerBytes[]转换出来的Layer图层一致。即底层对象序列化，反序列化结果内存地址一致、属同一引用对象。

PS.如下示例列形象地说明，我们预期想要的结果：
代码如下：
public class JsonText {

public static void main(String[] args) {
    User user = new User();
    user.setId(1);
    user.setUserName("xl");
    user.setAge(18);
    System.out.println("serialization before:" + user.getUserName());

    Gson gson = new Gson();
    String userString = gson.toJson(user);
    user = gson.fromJson(userString, User.class);
    System.out.println("serialization after:" + user.getUserName());
}

@Data
public static class User {
    private int id;
    private String userName;
    private int age;
}

}

PS:源对象User和序列化、反序列化原User对象一致。我们希望PadImage、Layer、TextLayer等亦能如此。
