            -Which commits I back-ported to 1.554.1 (current 'stable’ branch).
            I did so after this successful testing of ours:

            • jenkinsci /jenkins unit tests, for regression (passing ones kept passing);
            • jenkinsci /acceptance-test-harness, incl. both parent- and plugin-1st class-loading plugins (failures looked unrelated);
            • Ericsson-internal CLI ‘stress' tests, which used to reproduce JENKINS-22310; incl. parent/plugin-1st plugins, too;
            • brief manual testing through quick clicking-around, exercising some parent+plugin-1st (plugins) class-loading.

            Marco Miller: Those commit IDs do not exist in https://github.com/jenkinsci/jenkins, are they correct? Could you provide the URLs?

            I also confirm that both commits can be easily backported to 1.509.x and 1.532.x.
            We use fixes for about 1 week on 1.509.4...
