Java Swing JTable the proper way to remove rows

Problem .. removing the last row is throwing array out of index exception in the GUI scope!

solution ... make the removing action inside invokeLater block , this will make the GUI listeners work correctly

final DefaultTableModel model= ((DefaultTableModel)jTable.getModel());
SwingUtilities.invokeLater(new Runnable() {

@Override
public void run() {
model.removeRow(_row);
}
} );
