Jenkins Script Approval - List Jobs With Already Approved Methods

[RobC76]

Good morning,

  Within the Script Approvals page there is a section at the bottom that is listing the already approved signatures.  Jenkins is telling me that some may have introduced a vulnerability.  Before I clear these approvals I would like to find out which jobs call scripts that call these methods.  I've tried searching via the search box in the UI (no results), via the Script Console (I couldn't find any suitable Groovy code to do what I want) and using grep on the jobs folder on the Jenkins server (I couldn't find exact matches).  Is it at all possible to list jobs using specific method signatures?

  Regards
