XStream aliasing problem - generating "javassit" and junk characters

Question

I'm using XStream to convert my Hibernate entities to XML. All the entities were properly converted to XML until I changed the attributes to LAZY fetching. I see problems in aliasing.

I see some javassit code. However, this is happening to only one node. As you can see, for the "id2" it has aliased properly.

<foo> 
  <domain id="domainId" name="domainName" default="true">

    <com.mycomp.entity.Application___-_-__javassist__5 resolves-to="application"
id="id1" name="name1">
      ...
    </com.mycomp.entity.Application___-_-__javassist__5>

    <application id="id2" name="name2">
      ...
    </application>
  </domain> 
</foo>

thnak you :)
