If you are expecting getFetchSize() to return the size of the resultset,
that was nonstandard behaviour in the older driver. Newer drivers follow
the JDBC API specification and return whatever was set by setFetchSize()
(or an unspecified default value).

To get the resultset size portably, try something like:

   PreparedStatement stmt =
     connection.prepareStatement("...",
       ResultSet.TYPE_SCROLL_INSENSITIVE,
       ResultSet.CONCUR_READ_ONLY);
   // .. set parameters ..
   ResultSet rs = stmt.executeQuery();
   rs.last();
   int resultSetSize = rs.getRow();
