The tests were failing due a bug/feature gap uncovered with vectorized group by engine when grouping on numeric columns with null values (nulls are ignored and so results are incorrect). For this PR, I have temporarily added a check for `columnCapabilities.hasNulls().isFalse()` to disable vectorization if this is true (which it is for all expression virtual columns, so i had to add back a handful of `cannotVectorize()` calls to tests if sql compatible null handling is enabled). In a follow-up PR I will fix this feature gap for real to allow this to function again. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
