我有奇怪的问题，我不能固定。

我有 JDK 1.5 版本和基于 SSL 的通信通过套接字，只需发送和接收字符串数据。

try {
    KeyStore ks = KeyStore.getInstance("JKS");
    ks.load(new FileInputStream(
            "path_to_.jks"),
            "secret_of_jks".toCharArray());
    TrustManagerFactory tmf = TrustManagerFactory
            .getInstance(TrustManagerFactory.getDefaultAlgorithm());
    tmf.init(ks);
    KeyManagerFactory kmf = KeyManagerFactory
            .getInstance(KeyManagerFactory.getDefaultAlgorithm());
    kmf.init(ks, "secret_of_jks".toCharArray());
    SSLContext ctx = SSLContext.getInstance("TLS");
    ctx.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
    Socket s = ctx.getSocketFactory().createSocket("address_of_server", PORT);
    String jsonEx = "json text to send server";
    StringBuilder sb = new StringBuilder();
    sb.append(jsonEx.getBytes().length);
    sb.append("\r\n");
    sb.append(jsonEx);
    PrintWriter writer = new PrintWriter(s.getOutputStream(), true);
    writer.println(sb.toString());
    BufferedReader in =  new BufferedReader(new InputStreamReader(s.getInputStream()));
    System.out.println(in.readLine());
    writer.flush();
} catch (Exception e) {
    e.printStackTrace();
}

当我使用 JDK 1.7 + 一切正常，但是当我切换到 1.6-它抛出javax.net.ssl.SSLException: Connection has been shutdown: javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake

我的证书是 2048 加密的，我还安装了 JCE 无限强度管辖权策略http://www.oracle.com/technetwork/java/javase/downloads/jce-6-download-429243.html

如果有人感兴趣，这里是完全例外：

我刚刚发现，它们之间的区别是：
