In web-ui do:
select UID,* from com.j_spaces.examples.benchmark.messages.MessagePOJO where counter < 9 and rownum <10 order by counter
see that the first line has a counter 0 .
press the save icon, see that the results don't include the first raw (you have titles instead)
I have deploying a plane object and tested its generated csv file. it had all the rows needed.
