There is no configuration anywhere that would make use of fingerprints (e.g. in downstream jobs). Still Jenkins "always" writes fingerprints of jar files.
As far as I understood https://wiki.jenkins-ci.org/display/JENKINS/Fingerprint this should ony happen if configured explicitly.
Because of the huge amount of fingerprints (138206 for now) we're running into performance issues.
We're currently running 1.509.1 LTS
