      We are seeing repeatable very heavy lock congestion with FingerPrint.save.

      Jenkins apparently slides down to a state where a lot of threads have locked / are competing for a lock on FingerPrint instance and are competing for a lock on AnnotationMapper (a singleton). Everything grings to a halt.
