Closing JDialog by button?

Question

The item menu About of my JFrame is a JDialog that can be closed thanks to a but button as you can see below:

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         
    aboutDialog.this.dispose();
}

sometimes when I click on the close button of the JDialog, it actually closes the entire program.

I tried:

aboutDialog.this.setvisible(true)
aboutDialog.this.setDefaultCloseOperation(EXIT_ON_CLOSE);
aboutDialog.this.setDefaultCloseOperation(HIDE_ON_CLOSE);
aboutDialog.this.setDefaultCloseOperation(DISPOSE_ON_CLOSE);

But it didn't worked, any ideas?

`sometimes when I click on the close button of the JDialog, it actually closes the entire program.` - this will happen if the dialog is the only open window in your application. — camickr, May 07 '16 at 15:36
