I'm going to complain about this change too. It doesn't make a lot of
sense.
Let me describe what I'm reading, just to check: if there is a group
by, then iterate through all results to count them instead of getting
the count result as a single number.
If that is true, it means the database is ignoring the "COUNT(*)" when
there is a "GROUP BY", and I've never heard of a problem like that
before.
So, in fact this seems like it would BREAK a count when there is a
GROUP BY if the above statement is not true. It would result in a
single row with a count value, but the count value would be ignored by
this code, always returning 1 because there is only one row returned
(the row with the count).
Is there a test case for this or anything that was not working before
but is working after? If there isn't anything OOTB in OFBiz then let's
write something, like a unit test or something crazy like that.
