You don't use any of `JRobot` features, just use the `Robot` class: `new
Robot()`.

There must be `robot.waitForIdle` to ensure the UI becomes visible on the
screen before you get the location of the combo box on the screen.
It's also common to add `robot.delay(1000)`.

Swing is not thread-safe, you should get the location and size on EDT too.
Suggestion:
try {
SwingUtilities.invokeAndWait(() ->{
comboBoxLocation = comboBox.getLocationOnScreen();
comboBoxSize = comboBox.getSize();
closeButton.doClick();
});
}
catch (Exception e) {
throw new RuntimeException(e);

There's no need to catch the exception, just let it propagate.

I'm sure this line doesn't fit into 80-column limit, I recommend wrapping it.
Suggestion:
robot.mouseMove(comboBoxLocation.x + comboBoxSize.width - padding,
comboBoxLocation.y + comboBoxSize.height / 2);
Padding or offset could be a constant declared statically.
