ResultSet is closed

Jeg har den mest underlige fejl:

java.sql.SQLException: Operation not allowed after ResultSet closed
    at com.mysql.jdbc.ResultSet.checkClosed(ResultSet.java:652)
    at com.mysql.jdbc.ResultSet.next(ResultSet.java:5942)
    at com.kpw.blogwatch.ReportGenerator.getUrgencyBlogsInTimeFrame(ReportGenerator.java:217)


I denne metode:

public List<Blog> getUrgencyBlogsInTimeFrame(Date sincedate) {
        List<Blog> results = new ArrayList<Blog>();
        try {
            Statement stmt = con.createStatement();
            ResultSet rs = stmt.executeQuery("SELECT * FROM categorizedblog WHERE priority='3'");
            while(rs.next()) {
                String refindkey = rs.getString("refindkey");
                ResultSet rs2 = stmt.executeQuery("SELECT * FROM blog WHERE refindKey='" + refindkey + "' AND TIME_TO_SEC(TIMEDIFF('" + DatabaseFunctions.formatDateSQL(sincedate) + "',blogdate)) > 0");
                while(rs2.next()) {
                    Blog b = new Blog();
                    b.setRefindkey(rs2.getString("refindKey"));
                    b.setBlogdate(rs2.getTimestamp("blogdate"));
                    b.setTitle(rs2.getString("title"));
                    b.setUrl(rs2.getString("url"));
                    results.add(b);
                }
            }
        } catch (SQLException e) {
            e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
        }
        Collections.sort(results);
        Collections.reverse(results);
        return results;
    }


Linie 217 er while(rs.next()) {

Det er noejagtig samme standard teknik jeg bruger i alle andre metoder, men i denne her synes den resultsettet er closed...

Kan nogen se hvorfor?
