Lars Hofhansl updated PHOENIX-1281:
-----------------------------------
Description:
I looked through all callers of this method, and in each case we have a fresh
List object anyway, and hence the wrapping is not necessary saving at least one
new object per row scanned.
This is probably not really critical, but of a sizable COUNT(\*) or other
aggregate it still creates lot of unnecessary objects.
