Description

CoordinatorActionInfo coordInfo = coordEngine.reRun(jobId, rerunType, scope, Boolean.valueOf(refresh),
Boolean.valueOf(noCleanup));
coordActions = coordInfo.getCoordActions();

The Coordinator rerun command requires to acquire the lock before it executes. If it cant get the lock, then it is queued. In this case the return value, the coordInfo, is null. Trying to access the coordInfo causes NPE in such a case.
