scrollable ResultSet advise

Hi, i am just migrating from 7.4 to 8.3, and i have this issue:
In the old 7.4 days i wrote a simple function to get the size of a ResultSet.
public static int FS(ResultSet rs) throws SQLException{    /* fetch size */
        rs.last();
        int cnt = rs.getRow();
        rs.beforeFirst();
        return cnt;
}

However, in plain connnection.prepareStatement(String sql) calls, ResultSet type defaults to FORWARD_ONLY,
making the above code broken.

I am wandering if there is a quick way to solve this problem, without touching the huge number of PreparedStatements
in the code.
Has anyone solved this problem using some kind of a wrapper, e.g. using wrapper classes from jboss?
