Summary

0002439: com.caucho.sql.UserStatement.clearWarnings throwing NPE

Description

Trying to install JForum and testing it out. After configuring and starting up JForum, I encountered the attached exception error.

jforum's DbUtils.close() method code is as follows:

     public static void close(Statement st)
        {
                if (st != null) {
                        try {
                                st.clearWarnings();
                                st.close();
                        }
                        catch (SQLException e) { }
                }
        }

Resin is somehow not playing nice.
