IllegalStateException を発生させずに Java で ResultSet から JTable を設定するにはどうすればよいですか?

public static void main(String[] args) throws Exception {
    // Obtain the Connection
    
    ResultSet rs = stmt.executeQuery("select * from product_info");

    // Create and display the table
    JTable table = new JTable(buildTableModel(rs));

    // Close the Connection

    JOptionPane.showMessageDialog(null, new JScrollPane(table));

}

public static DefaultTableModel buildTableModel(ResultSet rs)
        throws SQLException {

    ResultSetMetaData metaData = rs.getMetaData();

    // Column names
    Vector<String> columnNames = new Vector<String>();
    int columnCount = metaData.getColumnCount();
    for (int column = 1; column <= columnCount; column++) {
        columnNames.add(metaData.getColumnName(column));
    }

    // Table data
    Vector<Vector<Object>> data = new Vector<Vector<Object>>();
    while (rs.next()) {
        Vector<Object> vector = new Vector<Object>();
        for (int columnIndex = 1; columnIndex <= columnCount; columnIndex++) {
            vector.add(rs.getObject(columnIndex));
        }
        data.add(vector);
    }

    return new DefaultTableModel(data, columnNames);

}
