> If a field (which is of type Tuple) in the data in null, POProject throws a
> NullPointerException. Also while projecting fields form a bag if a certain
> tuple in the bag does not contain a field being projected, an
> IndexOutofBoundsException is thrown. Since in a similar situation (accessing
> a non exisiting field in input tuple), POProject catches the
> IndexOutOfBoundsException and returns null, it should do the same for the
> above two cases and other cases where similar situations occur.
