Some counter points to backporting this were made on the mailing list.

TLS 1.0 and 1.1 are disabled by default starting from version 11.0.11, 8u292 and 7u301. Not all distributions kept the behaviour.

Amazon Corretto

Amazon decided to re-enable TLS 1.0 and 1.1 by default. This can be found in the release notes:

AdoptOpenJDK

To enable TLS 1.0 or 1.1 again you can alter the java.security file and remove TLSv1 or TLSv1.1 from the security property jdk.tls.disabledAlgorithms.
