Use of new String(String value) constructor in CXF codes ?

[Ivan]

While searching the codes, I saw that there are some cxf codes are using
new String(String value). like in StaxUtils, I am wondering is there any
special reason for this ?

public static Document read(XMLStreamReader reader, boolean recordLoc)
throws XMLStreamException {
        Document doc = DOMUtils.createDocument();
        if (reader.getLocation().getSystemId() != null) {
            try {
                doc.setDocumentURI(new
String(reader.getLocation().getSystemId()));
<-----------------------------------
            } catch (Exception e) {
                //ignore - probably not DOM level 3
            }
        }
        readDocElements(doc, doc, reader, true, recordLoc);
        return doc;
    }

Thanks
