On newly created ResultSet method first() shold have the same effect as method next() even for a ResultSet with 0 rows.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
See source code

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Internal rowPosition should be set to 1
ACTUAL -
Internal rowPosition is set to 0, 1, 2, ...

REPRODUCIBILITY :
This bug can be reproduced always.
