Steps:

2.create text field (textFieldTest1) and add in frame
3.create text field (textFieldTest2) and add in frame.
4. show frame
5.enter some text in textFieldTest1 and stay here.
6.Minimize frame.
7.Open again frame
8.The caret is invisible in textFieldTest1. I double click in textFieldTest1 but caret don't show. I can enter text again in textFieldTest1 but caret is invisible. I press left and right arrows in textFieldTest1 and enter text, but caret is invisible.It's very confuse.
9.Click mouse in textFieldTest2
10.Click mouse in textFieldTest1 and caret is now visible.
I think that this is a bug in swing.
What are think about this?

I meant for you to include code that I could cut and paste and execute to see if I had the same problem on my machine. I had to play with the code you gave to get it to compile. Make it easy for me to test. Anyway I did get it to compile and again it did work for me. here is the code I ended up testing:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
public class Main extends JFrame
     public Main()
super("Time");
setBounds(300, 200, 400, 200);
Container cont = this.getContentPane();
cont.setLayout(new GridBagLayout());
setDefaultCloseOperation(this.EXIT_ON_CLOSE);
JTextField textField1 = new JTextField(10);
cont.add(textField1);
cont.add(new JLabel("label1"));
JTextField textField2 = new JTextField(10);
cont.add(textField2);
cont.add(new JLabel("label2"));
setVisible(true);
     public static void main(String[] args)
          JFrame frame = new Main();
