https://github.com/jenkinsci/jenkins/pull/9326 merged the most recent release of the bouncycastle API plugin into the weekly release so that security scanners would not complain about the issues in earlier bouncycastle releases. That is included in Jenkins 2.461 weekly.

Backport to Jenkins LTS so that security scanners for the next LTS release are not complaining about an older version that is bundled with the Jenkins war file.
