@stephenconnolly has seen this personally and others have reported it as well. Needs better diagnosis.

Pushed better diagnostics to Stapler 1.224. When that gets integrated to core, we can track down the guilty plugin.

Got this from pending changes in script-security:
failed to serialize net.sf.json.JSONException: java.lang.reflect.InvocationTargetException for /jenkins/$stapler/bound/…/getClasspathRenderInfo given [org.kohsuke.stapler.bind.BoundObjectTable@6ef63dd5, org.kohsuke.stapler.bind.BoundObjectTable$Table@4e78f607, org.jenkinsci.plugins.scriptsecurity.scripts.ScriptApproval@2ab773a9]
from Function.bindAndInvokeAndServeResponse catching an exception and trying to render it, which seems inappropriate to me: surely the JavaScript caller is not expecting to get a Throwable even if one could somehow be serialized to JSON.
Attaching a demo plugin which produces this kind of error.
