Swing Textfield selectAll without invokeLater

Get rid of the evil invokeLater.
InvokeLater will pollute the UX design.

private class SelectAllOfFocus extends FocusAdapter {
 @Override
 public void focusGained(FocusEvent e) {
   if (! e.isTemporary()) {
     JFormattedTextField textField = (JFormattedTextField)e.getComponent();
     // This is needed to put the text field in edited mode, so that its processFocusEvent doesn't
     // do anything. Otherwise, it calls setValue, and the selection is lost.
     textField.setText(textField.getText());
     textField.selectAll();
   }
 }
}
