Https客户端失败，SSL Peer关闭不正确

Question

以下代码应该忽略所有证书：

public class Application {

public static void main(String... args) {

    System.out.println("Initiating... ");

    // Create a trust manager that does not validate certificate chains
    TrustManager[] trustAllCerts = new TrustManager[] { 
        new X509TrustManager() {     
            public java.security.cert.X509Certificate[] getAcceptedIssuers() { 
                return new X509Certificate[0];
            } 
            public void checkClientTrusted( 
                java.security.cert.X509Certificate[] certs, String authType) {
                } 
            public void checkServerTrusted( 
                java.security.cert.X509Certificate[] certs, String authType) {
            }
        } 
    }; 


     // Ignore differences between given hostname and certificate hostname
    HostnameVerifier hv = new HostnameVerifier() {
      public boolean verify(String hostname, SSLSession session) { return true; }
    };

    SSLContext sc = null;
    // Install the all-trusting trust manager
    try {
        sc = SSLContext.getInstance("SSL"); 
        sc.init(null, trustAllCerts, new java.security.SecureRandom()); 
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
        HttpsURLConnection.setDefaultHostnameVerifier(hv);
    } catch (GeneralSecurityException e) {
    } 
    // Now you can access an https URL without having the certificate in the truststore
    try { 
        URL url = new URL("https://localhost:30009/iPG/c2b/multione"); 
        HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();
        conn.setSSLSocketFactory(sc.getSocketFactory());
        conn.setHostnameVerifier(hv);
        InputStream is = conn.getInputStream();
        InputStreamReader isr = new InputStreamReader(is);
        BufferedReader br = new BufferedReader(isr);

        String inputLine;

        while ((inputLine = br.readLine()) != null) {
            System.out.println(inputLine);
        }

        br.close(); 
    } catch (Exception e) {
        e.printStackTrace();
    } 

}

}

但是我一直收到错误：

我不明白为什么会这样。
