David Handermann commented on NIFI-8630: ---------------------------------------- Thanks for submitting this issue [~branko.peshevski]! The Java Mail reference implementation is now named [Jakarta Mail|https://eclipse-ee4j.github.io/mail/] so dependency updates should leverage those libraries. > PutEmail fails to negotiate TLS1.2 with latest JDK. > ---------------------------------------------------- > > Key: NIFI-8630 > URL: https://issues.apache.org/jira/browse/NIFI-8630 > Project: Apache NiFi > Issue Type: Bug > Reporter: Branko Peshevski > Priority: Critical > > On April 20, 2021 with the latest JDK the support for TLS 1.0 and 1.1 was > removed/disabled.
