    To reproduce in {{2.14-SNAPSHOT}}: * start on a new home * swat aside the setup wizard * install {{github-branch-source}} including all dependencies * manually upload {{workflow-scm-step-2.0.hpi}} (downgrading from the 2.2 installed from the UC) * restart You will see a warning about cyclic dependencies: {code:none} ... hudson.PluginManager$1$3$2$3 reactOnCycle SEVERE: found cycle in plugin dependencies: (root=Plugin:workflow-scm-step, deactivating all involved) Plugin:workflow-scm-step -> Plugin:git -> Plugin:workflow-scm-step {code} Which looks fine (you need to update {{workflow-scm-step}} to solve the conflict) until you realize it is disabling {{git}} but not its dependencies.

These steps to reproduce are somewhat artificial. The original report comes from CloudBees Jenkins Enterprise: after starting 1.642.4.1 and installing {{subversion}} from the update center, Jenkins will not start (though in that case the fatal error comes a little later and lacks the "in a bad way" message.
