我试图连接到带有加密的Web服务器。 Web服务器仅允许使用TLSv1.2协议的连接。Java 7和TLSv1.2套接字

public class SSLSocketClient {

try {
String host = "172.20.172.106";
SSLSocketFactory factory =

SSLSocket socket = (SSLSocket) factory.createSocket(host, 443);
String[] protocols = socket.getEnabledProtocols();
System.out.println("Enabled Protocols: ");

* PrintWriter catches all IOExceptions (including
* SSLExceptions), sets an internal error flag, and then
* returns without rethrowing the exception.
*
* Unfortunately, this means any error messages are lost,
* which caused lots of confusion for others using this
* code. The only way to tell there was an error is to call
* PrintWriter.checkError().

如果我运行JRE验证码8一切正常修改这个片段现在。
这是输出我得到

JDK7应该支持TLSv1.2工作，但我不” t看到它在支持的协议输出
