------------------------------------------------
Code changed in jenkins

http://jenkins-ci.org/commit/jenkins/99385dcd1c8a2dc84d51133f1f4b06d4bc1cf653
Log:
[FIXED JENKINS-12302] Refactor anonymout class for loading groovy script into
separate class as static block (due to inheritance of outer class from
CLICommand) initialization leads to NPE (namely in Jenkins.getInstance
Jenkins.getInstance().getPluginManager())
(cherry picked from commit 7bdc1790166198de93b2b7c58286d9554be967b4)
