Cannot seem to move war/src/main/webapp/help/user/*.html since there is no Descriptor to bind doHelp to.

f43a450c addendum: during migration, if nothing else is being fingerprinted besides archived artifacts, then there is no reason to keep the separate fingerprint publisher at all.

Some loggers may show the thread name anyway, but /log/* in the UI at least does not.
And recent versions of Jenkins are being improved to capture lots of context in the thread name;
an unreleased improvement in Stapler includes the Jelly views being rendered.

For icons not defined in the IconSet

prevent build index page to redirect anonymous user to login just because some artifact share fingerprints with another job

Anyway the originally reported stack trace looks like it could no longer happen, due to more robust model classes.
