Bagaimana untuk Mengisi JTable dari ResultSet dan Elakkan IllegalStateException?

public static DefaultTableModel buildTableModel(ResultSet rs)
        throws SQLException {

    ResultSetMetaData metaData = rs.getMetaData();

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

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

    return new DefaultTableModel(data, columnNames);

}

JTable table = new JTable(buildTableModel(rs));

public class GUI extends JFrame {

    // ...

    private void loadData() {
        button.setEnabled(false);

        try (Connection conn = DriverManager.getConnection(url, usr, pwd);
             Statement stmt = conn.createStatement()) {

            ResultSet rs = stmt.executeQuery("select * from customer");
            ResultSetMetaData metaData = rs.getMetaData();

            // ...

            while (rs.next()) {
                // ...
            }

            tableModel.setDataVector(data, columnNames);
        } catch (Exception e) {
            // ...
        }
        button.setEnabled(true);
    }

}
