ScrollableResults javadoc stands:
{{ /**

• Get the current position in the results. The first position is number 0 (unlike JDBC).
  *
• @return The current position number,* numbered from 0*; -1 indicates that there is no current row
  */}}
  Those requirements are obviously not fulfilled by both ScrollableResultsImpl and FetchingScrollableResultsImpl implementations that does not returns the sames values at the same result position. Moreover, a FetchingScrollableResultsImpl does not accept setRowNumber(0).
