/**
 * Originally copied from javax.swing.JEditorPane.
 * <p>/* w  w w . j a v  a  2 s  .co m*/
 * Fetches a stream for the given URL, which is about to
 * be loaded by the <code>setPage</code> method.  By
 * default, this simply opens the URL and returns the
 * stream.  This can be reimplemented to do useful things
 * like fetch the stream from a cache, monitor the progress
 * of the stream, etc.
 * <p>
 * This method is expected to have the the side effect of
 * establishing the content type, and therefore setting the
 * appropriate <code>EditorKit</code> to use for loading the stream.
 * <p>
 * If this the stream was an http connection, redirects
 * will be followed and the resulting URL will be set as
 * the <code>Document.StreamDescriptionProperty</code> so that relative
 * URL's can be properly resolved.
 *
 * @param page the URL of the page
 * @param followRedirects Follow redirects.
 * @param timeout The read timeout.
 * @param userName The user name to use for the connection.
 * @param userPassword The password to use for the connection.
 * @throws IOException if something went wrong.
 * @return a stream reading data from the specified URL.
