XStream with Dom4J driver fail to handle self object reference

• JDK version and platform:

  sun jdk 1.5.0_07 for windows

marshal object with follow member create wrong reference attribute in xml file
wrong xml output only occurs if dom4j driver is used.

class BadSelfReference implements Serializable {
private static final long serialVersionUID = 38772160335615698L;
private BadSelfReference owner = this;
private String aString = "1234";
private Long aLong = new Long(500);
// getter setter omitted
}

output
<testcase.BadSelfReference>
<owner reference=".."/>
<aString reference="..">1234</aString>
<aLong>500</aLong>
</testcase.BadSelfReference>

how ever, the following class can marshal correctly

class GoodSelfReference implements Serializable {
private static final long serialVersionUID = 38772160335615698L;
private String aString = "1234";
private Long aLong = new Long(500);
private GoodSelfReference owner = this;
// getter setter omitted
}

output

<testcase.GoodSelfReference>
<aString>1234</aString>
<aLong>500</aLong>
<owner reference=".."/>
</testcase.GoodSelfReference>
