        /* According to the XML 1.0 specifications, when there is an XML declaration
         * at the beginning of an XML document, it is invalid to have
         * white spaces before that declaration (reminder: a XML declaration looks like:
         * <?xml version="1.0" encoding="UTF-8"?>). In contrast, when there is no XML declaration,
         * it is valid to have white spaces at the beginning of the document.
         *
         * When they send a NETCONF message, several NETCONF servers start with a new line (either
         * LF or CRLF), presumably to improve readability in interactive sessions with a human being.
         * Some NETCONF servers send an XML declaration, some others do not.
         *
         * If a server starts a NETCONF message with white spaces and follows with an XML
         * declaration, XmlUtil.readXmlToDocument() will fail because this is invalid XML.
         * But in the spirit of the "NETCONF over SSH" RFC 4742 and to improve interoperability, we want
         * to accept those messages.
         *
         * To do this, the following code strips the leading bytes before the start of the XML messages.
