HTTPUrlConnection does not download the whole page

I have a problem with this code, as you can see in print, where it
prints the error in the page's code:

public void print(String link) {

        String page = this.getPage(link);

        // Here I can see the error as it prints the error in the
page's code
        System.out.println(page);
        System.err.println("1234567890+");
}

public String getPage(String link) {

        String pageEscaped = "";

        try {

            URL url = new URL(link);

            // Open the Connection
            HttpURLConnection conn = (HttpURLConnection)
url.openConnection();

            // Set the information
            conn.setRequestProperty("user_agent", "Mozilla/5.0
(Windows; U; Windows NT 6.0; da-DK; rv:1.9.1.4) Gecko/20091016 Firefox/
3.5.4 (.NET CLR 3.5.30729)");
            conn.setRequestProperty("max_redirects", "0");
            conn.setRequestProperty("timeout", "300");
            conn.setRequestMethod("GET");
            conn.setDoOutput(true);

            // Connect
            conn.connect();

            // Get the Status-Code and add it to the HashMap
            int statusCode = conn.getResponseCode();

            String page = this.getPage(conn.getInputStream());

            pageEscaped = StringEscapeUtils.unescapeHtml(page);

            conn.disconnect();

        } catch (IOException e) {System.err.println(e.getCause
());System.err.println(e.getMessage());}

        return pageEscaped;
}

public String getPage(InputStream is) throws IOException {

        BufferedReader br = new BufferedReader(new InputStreamReader
(is));
        String line = "";
        StringBuilder sb = new StringBuilder();

        while ((line = br.readLine()) != null) {

            sb.append(line+'\n');
            System.out.println(line);
        }

        return sb.toString();
}
