    • Jenkins 1.501 / Tomcat 6 / JDK 1.6.0_18 / Debian 6 / x86
      IE 9

      Jenkins 1.501 was running stable / no problem is log.
      Then I added "JaCoCo" plugin from Update Center and restarted Jenkins.
      When booting, Jenkins then scared me to death with a stack trace:

      Obviously it has a problem with the GIT plugin now – but I didn't touch that one, and it worked well before. Also, the GIT plugin seems to work fine, still.

      As all works well, maybe the only bug is that the WARNING is actually printed?

          It does not look like a problem with the git plugin. It looks like some other class is asking to Jenkins about the git plugin, and Jenkins not being able to find it. It might be because this request could happen before the git plugin is actually loaded.
          Just my 2 cents

          mkarg, do you have any motivation to work on this issue? Otherwise I would close it, as I assume nobody else will ever address this again after 3 years now.

          I would love to help fixing the bug, but honestly I am booked out with other open source projects.
