If CookieManager.get() is called with an URI that does not contain a path, e.g "http://www.sun.com" instead of "http://www.sun.com/", it does not return any cookies, even if CookieManager contains cookies for the URI.

The relevant code is:

    /*
     * path-matches algorithm, as defined by RFC 2965
     */
    private boolean pathMatches(String path, String pathToMatchWith) {
        if (path == pathToMatchWith)
            return true;
        if (path == null || pathToMatchWith == null)
            return false;
        if (path.startsWith(pathToMatchWith))
            return true;

        return false;
    }

That needs to cater for the case where path is the empty string.
