How can I set JavaFX dialog height?

Question

How can I set JavaFX alert height in which dialog's contentText is null ? I made an alert and set contentText as null, but dialog's contentText field's height does not became smaller. How can I make contentText field's height as minimum?

Alert alert = new Alert(AlertType.CONFIRMATION);
alert.setTitle("title");
alert.setHeaderText("I want to make dialog without contenttext");
alert.setContentText(null);    //this is null but this field is still remain

I just tried like this.

alert.getDialogPane().setMaxHeight(10); //does not work.

Using this method you can customize the size of the alert.

alert.getDialogPane().setMaxSize(2,2);
