Method
protected void writeObject(Object o) of class java.beans.XMLEncoder
does not write java.awt.Cursor object to the output stream.

Here is minimized test:
import java.io.*;
import java.beans.*;
import java.awt.*;

public class Test0010 {

    public static void main(String[] args) {

        Cursor object = new Cursor(java.awt.Cursor.TEXT_CURSOR);

        ByteArrayOutputStream os = new ByteArrayOutputStream();
        XMLEncoder xmlEnc = new XMLEncoder(os);
        xmlEnc.writeObject(object);
        xmlEnc.flush();
        xmlEnc.close();

        ByteArrayInputStream in = new ByteArrayInputStream(os.toByteArray());
        XMLDecoder xmlDec = new XMLDecoder(in);
        System.out.println("OutputStream");
        System.out.println(os.toString());

        Cursor res = (Cursor) xmlDec.readObject();
        if(res.getType() == java.awt.Cursor.TEXT_CURSOR) {
            System.out.println("OKAY");
        } else {
            System.out.println("Failed");
            System.out.println("Cursor type: " + res.getType());
            System.out.println("Should be : " + java.awt.Cursor.TEXT_CURSOR);
        }
    }
}
