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);                 }                 } );

private TextView result; private String barCode=""; @Override public boolean onKeyDown(int keyCode, KeyEvent event) { char pressedKey = (char) event.getUnicodeChar(); if(result==null){ // System.out.println("result=null"); result=(TextView)findViewById(R.id.scanResult); } barCode+=pressedKey; if(event.getKeyCode()==KeyEvent.KEYCODE_ENTER){ result.setText(barCode); barCode=""; } return super.onKeyDown(keyCode, event); }
