Affected apps can re-enable these versions of TLS because they aren’t being removed from the JDK.
The change will apply to at least OpenJDK 8u292 onward, OpenJDK 11.0.11 onward, and all versions of OpenJDK 16, following the JRE and JDK Crypto Roadmap published by Oracle.Īpplications that update to a JDK with this change may see outages if they are currently using TLS 1.0/1.1, either to connect to endpoints that don’t support at least TLS 1.2 (client scenario) or serving traffic to clients that don’t support TLS 1.2 (server scenario).
Java applications using TLS to communicate will need to use TLS 1.2 or above to establish a connection. OpenJDK will be disabling TLS 1.0 and 1.1 availability by default in the security.properties file.

This post describes the situation in more detail, explains how to re-enable older TLS versions on non-Corretto distributions if necessary, and provides ideas for auditing traffic. Feedback from customers and industry partners suggests that this deprecation has the potential to cause outages, so Amazon will be giving Corretto users a chance to audit their usage of TLS and take necessary measures before disabling these older protocols. Amazon Corretto will be keeping TLS1.0 and TLS1.1 available by default for a while longer. Starting on April 20, 2021, quarterly update releases of OpenJDK are disabling TLS1.0 and TLS1.1 availability by default in all versions of OpenJDK.
