added a comment - okay, I was able to get this running again by manually rolling back trilead-api to 1.67.vc3938a_35172f. It looks like it's a JDK 8 issues. I thought I had until September 1st before things like this would break.

added a comment - I just got burned by this same issue. Running Jenkins 2.346.2 on Java 8; now have Trilead API Plugin
Version1.71.v9e7860a_67a_df and my syslog is filling up with:
jenkins[1803]: java.lang.UnsupportedClassVersionError: com/trilead/ssh2/crypto/cipher/BlockCipher has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
I foolishly assumed upgrading would be safe because other plugins had notes saying they weren't updating to the latest available version, so I figured they would not install on an unsupported Java version. Shame on me for not searching for the Trilead release notes!

added a comment - I'm running Jenkins 2.346.2 on JRE 11, however some agents our teams use are still running on JRE 8, and trying to run jobs on them results in this error.

Could you confirm the trilead-api plugin version, Jenkins Core version, and JDK you are using?
If you are using the latest version of trilead-api on a JDK 8 the release notes warm about is no longer compatible with Java 8.
