XStream cannot properly unmarshal Calendar with different TimeZone

The unmarshaled Calendar instance uses the default time zone.

public void testCalendar()

{ final Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("UTC")); final XStream xstream = new XStream(); final String xml = xstream.toXML(cal); final Calendar serialized = (Calendar)xstream.fromXML(xml); assertEquals(cal, serialized); }
