Buggy source:
public SearchDialog(){
  setDefaultCloseOperation(JDialog.HIDE_ON_CLOSE);
  Container cnt=getContentPane();
  setSize(400,150);
  cnt.setLayout(new BoxLayout(cnt,BoxLayout.PAGE_AXIS));
  JPanel panButtons=new JPanel(new FlowLayout());
  JButton okButton=new JButton(translate("String_Node_Str"));
  okButton.setActionCommand(ACTION_OK);
  okButton.addActionListener(this);
  JButton cancelButton=new JButton(translate("String_Node_Str"));
  cancelButton.setActionCommand(ACTION_CANCEL);
  cancelButton.addActionListener(this);
  panButtons.add(okButton);
  panButtons.add(cancelButton);
  JPanel panField=new JPanel(new FlowLayout());
  searchField.setPreferredSize(new Dimension(250,searchField.getPreferredSize().height));
  panField.add(new JLabel(translate("String_Node_Str")));
  panField.add(searchField);
  cnt.add(panField);
  JPanel checkPanel=new JPanel(new FlowLayout());
  checkPanel.add(ignoreCaseCheckBox);

}

Fixed version (ground truth):
public SearchDialog(Window owner){
  super(owner);
  setDefaultCloseOperation(JDialog.HIDE_ON_CLOSE);
  Container cnt=getContentPane();
  setSize(400,150);
  cnt.setLayout(new BoxLayout(cnt,BoxLayout.PAGE_AXIS));
  JPanel panButtons=new JPanel(new FlowLayout());
  JButton okButton=new JButton(translate("String_Node_Str"));
  okButton.setActionCommand(ACTION_OK);
  okButton.addActionListener(this);
  JButton cancelButton=new JButton(translate("String_Node_Str"));
  cancelButton.setActionCommand(ACTION_CANCEL);
  cancelButton.addActionListener(this);
  panButtons.add(okButton);
  panButtons.add(cancelButton);
  JPanel panField=new JPanel(new FlowLayout());
  searchField.setPreferredSize(new Dimension(250,searchField.getPreferredSize().height));
  panField.add(new JLabel(translate("String_Node_Str")));
  panField.add(searchField);
  cnt.add(panField);
  JPanel checkPanel=new JPanel(new FlowLayout());
  checkPanel.add(ignoreCaseCheckBox);
  checkPanel.add(regexpCheckBox);
  cnt.add(checkPanel);
  ButtonGroup group=new ButtonGroup();
  group.add(searchInASRadioButton);
  group.add(searchInTextsRadioButton);
  JPanel rbPanel=new JPanel(new FlowLayout());
  searchInASRadioButton.setSelected(true);
  searchInTextsRadioButton.setSelected(false);
  rbPanel.add(searchInASRadioButton);
  rbPanel.add(searchInTextsRadioButton);
  cnt.add(rbPanel);
  cnt.add(panButtons);
  getRootPane().setDefaultButton(okButton);
  View.centerScreen(this);
  setIconImage(View.loadImage("String_Node_Str"));
  setTitle(translate("String_Node_Str"));
  setModalityType(ModalityType.APPLICATION_MODAL);
  pack();
