> RexImpTable implements {{IS EMPTY}} and {{IS NOT EMPTY}} using {{Collections.isEmpty()}} but declares them as {{NullPolicy.NONE}}. This causes nullable array and map columns to throw NPE at execution time when hitting null values. I strongly suspect that other collection operators are similarly misclassified and would run in to issues is used against nullable types.
