> This bug was introduced in the fix for PHOENIX-4791.
> When projecting array elements in hash join, we now generate both ProjectedTupleValue and MultiKeyTupleValue. Before the fix for PHOENIX-4791, hash join was only generating ProjectedTupleValue, and there were two lines of code with class casts that reflected this assumption. The fix is to handle both ProjectedTupleValue and MultiKeyTupleValue, while continuing to propagate the array cell as in PHOENIX-4791.
