Java 7 support of AES-GCM in SSL/TLS?

Question

According to Java 7 documentation as well as third party vendors, it appears Java 7 should support AES-GCM suites:

1. ibm java 7
2. java 7 ssl doc

Answer 1

There are no GCM cipher suites in the SunJSSE Provider of Java 7 (assuming an Oracle JRE), although it supports TLS 1.2.

These have been introduced in Java 8 (see cipher suite table in the "The SunJSSE Provider" section).

1.8.0-ea-b124    
Connecting with 71 cipher suites supported:
