I see java.lang.NoClassDefFoundError: javax/servlet/ServletException happening on agent side when loading these as lambdas. Happened on fresh agents (kubernetes agents) when running Jenkins through hpi:run, but also on permanent agent, as long as I clear jarCache.

Not sure where the class is being captured from, but moving these to standalone classes definitely fixes the issue I'm seeing.

Similar to jenkinsci/git-client-plugin#171, jenkinsci/git-client-plugin#359, it has been a long time since I've seen this kind of issue
