【问题描述】：
根据 Java 7 文档以及第三方供应商，Java 7 似乎应该支持 AES-GCM 套件：
我在客户端和服务器之间的协商中遇到了一些错误，无法协商密码，因为它仅限于 AES-GCM 密码。经过调查，我发现客户端和服务器（tomcat 实例）似乎不支持密码套件。在客户端运行一些示例代码以获取输出：
// Create an SSLContext that uses our TrustManager
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, trustAllCerts, new SecureRandom());
SSLParameters params = context.getSupportedSSLParameters();
String[] suites = params.getCipherSuites();
System.out.println("Java version : " + System.getProperty("java.runtime.version"));
System.out.println("Connecting with " + suites.length + " cipher suites supported:");
for (int i = 0; i < suites.length; i++) {
System.out.println();
System.out.print(" ********* ");
System.out.print(suites[i]);
System.out.print(" ********* ");
}
Java version: 1.7.0_51-b13
Connecting with 63 cipher suites supported:

不知道有没有人遇到过这样的问题。
Java 7 是否支持在 SSL/TLS 中使用 AES-GCM？
