Mamta A. Satoor commented on DERBY-2979:
----------------------------------------

Manjula, I just have one minor comment. I noticed that except one change, all the other changes in the patch look for <= 0. But one change (towards the end in the patch) looks as follows 
if (count == 0)
Should we be checking for <= 0 rather than == 0, ie is it possible for count to have a value less than 0?
