      Git Plugin 2.3.4 (same results with 2.4.0)
      Git client plugin 1.19.0
      BitBucket plugin 1.1.2

      We have set up Jenkins to trigger polling on a number of branches whenever someone pushes to BitBucket, quite a common setup I would assume.

      Now for about two weeks, these requests start to fail after a while after every Jenkins restart. We tried updating Jenkins, all packages and recently downgrading the git plugin, none of which changed anything.

      We can replicate this locally by doing something like a curl https://USERNAME:PASSWORD@jenkins.riskmethods.net/git/notifyCommit?url=git@bitbucket.org:riskmethods/riskmethods.git.

      Here is the backtrace:

          There is a missing null check in the Jenkins core. I'm not sure about the cause of the null job (persisted data?), but the core should be updated in any case
