Answers a String representing the next line of text available in this BufferedReader. A line is represented by 0 or more characters followed by '\n', '\r', "\n\r" or end of stream. The String does not include the newline sequence. @return String the contents of the line or null if no characters wereread before end of stream. @throws IOException If the BufferedReader is already closed or some other IO error occurs.

        randomAccessFile.seek(offset);
        //log.debug("SKIP IS ::" + offset);


        String line = null;
        String lineUTF8 = null;
        while ((line = randomAccessFile.readLine()) != null) {
