jvYaml - round-tripping for entity/ class

Hello, I'm getting an error, and I'm stuck. Here are my three classes:

public class TestEntity {
   public TestEntity () {}
   public TestEntity (int v) {this.val = v;}
   public int val = 987;
   public int getVal () {return val;}
   public void setVal (int i) {this.val = i;}
}


import java.awt.Dimension;
import java.util.*;

public class BigEntity {

   private List props = new LinkedList();
   public List getProperties () {return props;}
   public void setProperties (List props) {this.props = props;}

   private String name = "Jo";
   public String getname () {return name;}
   public void setname (String n) {this.name = n;}

   public BigEntity () {
      props.add(new TestEntity());
      props.add(new TestEntity(55));
   }
   public BigEntity (String name) {this.name = name;}

   public boolean equals (Object other) {
      boolean ret = this == other;
      if (!ret && other instanceof BigEntity) {
         BigEntity o = (BigEntity)other;
         ret = this.name == null ? o.name == null : this.name.equals(o.name);
      }
      return ret;
   }
   public int hashCode () {return 3 * (name == null ? 0 : name.hashCode());}
   public String toString () {return "#<BigEntity name=\"" + name + "\">";}
}


import java.io.*;
import java.util.*;
import org.jvyaml.YAML;

public class MyDriver {
   public static void main (String[] args) { try {
      //// Dump test:
      BigEntity e1 = new BigEntity();
      String filename = "t.yaml";
      YAML.dump(e1, new FileWriter(filename));
      System.out.println(YAML.dump(e1)); // debug
      //// Load Test:
      BigEntity e2 = (BigEntity)YAML.load(new FileReader(filename));
      System.out.println("e2 = " + e2);
   } catch (Exception e) {e.printStackTrace();} }
}


And when I run java MyDriver, this is the output:

$ java MyDriver 
--- !java/object:BigEntity
name: Jo
properties: !!seq:java.util.LinkedList
- !java/object:TestEntity
  &id1 val: 987
- !java/object:TestEntity
  *id1: 55

        at org.jvyaml.YAML.load(YAML.java:165)
        at MyDriver.main(MyDriver.java:12)


Can anyone please explain what I'm doing wrong.

Can anyone explain why in the entity dump (first part of test run
output), I'm getting &id1 and *id1 ??

Thanks in advance
Zen
