> From the mailing list, a user reported a bug in which they were using
> multiple instances of From.formattedFile TableSources and were seeing records
> getting dropped at random from different runs of their jobs. I created a
> simple test that replicated the behavior and found the source of the problem
> in the planner: a confusion between a BaseInputTable and the
> BaseInputCollection objects that does most of the work to actually configure
> the input table data that resulted from BaseInputTable's equals() method not
> checking to see if an object was of its same class before performing the
> comparison on the underlying BaseInputCollection instance.
