> OOZIE-1879 fixes a problem where the order of actions that the actions in a
> fork ended can be different than when they are executed during a rerun,
> resulting in an error. It does this by using a comparator to sort them into
> the proper order in LiteWorkflowInstance. However, the code assumes that all
> actions in the executionPath have an end time, which is not always true. If
> that happens, you get an NPE like this:
> {noformat}
> java.lang.NullPointerException
