Reserialized String not equal in

The following test fails with version 1.0.1, and the snapshot.jar from the download page:

public void testSlashRSlashSlashSlashN(){
StringBuffer sb = new StringBuffer().append('\r').append('\\').append('\n');
XStream xstream = new XStream();
String before = sb.toString();
String xml = xstream.toXML(before);
String after = (String)xstream.fromXML(xml);
assertEquals("strings don't match",before,after);
}
