Don't you want to check cpTasks for being null?

> Reporter: Sachin Goel

>
> Distributed cache files cannot be accessed when working in Iterative
> contexts. While constructing the context in {{AbstractIterativePactTask}},
> the distributed entries are not passed on to runtime context.
> My commit will add this and also unify the distributed cache system to work
> everywhere, including in the Collection Environment.
