      My jenkins version is : Jenkins 2.401.1

      I have a github repo : repoA, it has many branches, webhook is setup and has been working for a few years ( spray method)

      One jenkins, there job: testJob, it is freestyle project, with GitHub hook trigger for GITScm polling selected,  Source Code Management pointed to this repoA, Branch Specifier is **, it has been working for years.

      there was recent jenkins upgrade and plugin upgrade, 

      Issue:

      I did a change on testBranch1, commit on Github, testJob got poked ( I can see this from log), but the job starts to build all branches, as if the jenkins thinks all branches have been changed. There is only change on 1 branch.

      Some debug info

      GitHubPollLog shows **

          Li added a comment -

          I did more digging, the GitHubPollLog shows :

           > git log --full-history --no-abbrev --format=raw -M -m 7dc947b4411462c81b2b311624833fc024e62cfc..a4089230452868ecfb1fc9cd4a817f61f9bafc1b # timeout=10

          Totally wrong infos, Then I checked the job build.xml and log, all wrong info like 

          <string>GIT_COMMIT</string> in build.xml

          also from log, I can see this:

          JENKINS-19022: warning: possible memory leak due to Git plugin usage; see: https://plugins.jenkins.io/git/#remove-git-plugin-buildsbybranch-builddata-script
