I have a java based client (using java 1.6.30) that opens an SSL connection to my server deployed on Tomcat 7.0.26. Tomcat is using Java 6 and in the server.xml I configured the connector to use sslProtocol="TLS".
I wonder what is the SSL version being used? Is it TLS1.0? TLS1.1? Something else?

Show activity on this post. Get the SSLSession from your SSLSocket on your client and use its getProtocol() method. Oracle JRE/OpenJDK 6 supports SSLv3 and TLS 1.0. You would need at least the IBM JRE 6/7 or Oracle JRE/OpenJDK 7 to get support for TLS 1.1 and TLS 1.2.
The JDK 11 release includes an implementation of the Transport Layer Security (TLS) 1.3 specification (RFC 8446). For more details including a list of the features that are supported, refer to the Java Secure Socket Extension (JSSE) Reference Guide documentation and JEP 332.
And while Java 7 supports TLSv1. 2, the default is TLS v1.

Oracle JRE/OpenJDK 6 supports SSLv3 and TLS 1.0. You would need at least the IBM JRE 6/7 or Oracle JRE/OpenJDK 7 to get support for TLS 1.1 and TLS 1.2. (This is also related to the available cipher suites, as mentioned in this question.)
