Why does this code cause a StackOverflowError

Question

I am trying to close a window when OK button is pressed. But when I try to run the file, it gives me a StackOverflowError.

Here is my code:

public class Test1 extends javax.swing.JFrame {

Test1 t = new Test1();
/**
 * Creates new form Test1
 */

public Test1() {
    initComponents();
}

And this is the actionListener for the button.

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
        t.setVisible(false);
    }

This is the error message,

Exception in thread "AWT-EventQueue-0" java.lang.StackOverflowError
    at sun.awt.Win32GraphicsConfig.getBounds(Native Method)
    at sun.awt.Win32GraphicsConfig.getBounds(Win32GraphicsConfig.java:222)

    at Test1.<init>(Test1.java:13)
    at Test1.<init>(Test1.java:13)
    at Test1.<init>(Test1.java:13)
    at Test1.<init>(Test1.java:13)
    at Test1.<init>(Test1.java:13)
    ...and so on

Test1.java:11 refers to public class Test1 extends javax.swing.JFrame and Test1.java:13 refers to Test1 t = new Test1();

What is the problem here? How can I solve it?

`Test1 t = new Test1();` really? A new `Test1` creates a new `Test1` creates a new `Test1`, .... — tkausl, Oct 12 '16 at 10:53
To the downvoter(s), I don't think downvoting a question because the solution is trivial or the error is stupid is a good way to use voting. — Federico klez Culloca, Oct 12 '16 at 10:56
I'm voting for reopening because the question is not asking what a stack overflow is, but what in this specific code is causing it. — Federico klez Culloca, Oct 12 '16 at 10:58
