null pointer exception

[Bihuan Chen]

Hi,

The following two methods may receive a uri with undefined scheme. Thus getScheme() may return null, which causes a null pointer exception. The similar problem may arise in hprose.client.HproseTcpClient. Although it is clearly stated in the wiki that only http and tcp are supported, it is better to add such null checks.

public static HproseClient hprose.client.HproseHttpClient.create(String uri, HproseMode mode) throws IOException, URISyntaxException {
        String scheme = (new URI(uri)).getScheme().toLowerCase();
        if (!scheme.equals("http") && !scheme.equals("https")) {
            throw new HproseException("This client doesn't support " + scheme + " scheme.");
        }
        return new HproseHttpClient(uri, mode);
}

public static HproseClient hprose.client.HproseHttpClient.create(String[] uris, HproseMode mode) throws IOException, URISyntaxException {
        for (int i = 0, n = uris.length; i < n; ++i) {
            String scheme = (new URI(uris[i])).getScheme().toLowerCase();
            if (!scheme.equals("http") && !scheme.equals("https")) {
                throw new HproseException("This client doesn't support " + scheme + " scheme.");
            }
        }
        return new HproseHttpClient(uris, mode);
    }
