> This bug was introduced in the fix for PHOENIX-4791.
> When projecting array elements in hash join, we now generate both ProjectedTupleValue and MultiKeyTupleValue. Previously, we were only generating ProjectedTupleValue, and there are two lines of code that contain this assumption in class casts. The fix is to merge into the MultiKeyTupleValue, while propagating the array cell as in PHOENIX-4791.
