    Description

      I'm running Jenkins 1.492. Version 0.9 of the Dependency Graph View Plugin works fine but when I upgrade it to version 0.10 several jobs (AFAICS randomly) fail to load on Jenkins startup. In the log I noticed:

      Seeing the line with TaskGraphBuilder I tried downgrading the plugin to the 0.9 version and all the jobs work fine again. Tried upgrading to 0.10 again and jobs start failing to load, so AFAICT the Dependency Graph View Plugin seem to be involved in the "Jenkins fails to load jobs" problem I'm stumbling upon.

      If you need any further information please let me know.
