Your report is difficult to understand, as you don't provide the
complete source code (that's why I just ignored it the first time).

Even if it looks like it should be OK, there are several informations
that you've ommitted, but which are important for understanding what
happens.

For example:
- what is offset, and what is rows (and in turn, what is their
  output operator)
- in what ways are the results different?
- since this looks like distributed code: could any of the
  objects involved change behind the szenes?

In short, chances are that the bug is in your code.
