This was a closed test. It fails very rarely due to completely incorrect colour sampling by Robot. I had this happen to me when the window came up behind some other window on my desktop. So the "fix" here is to use setAlwaysOnTop(true) But so far as I can see there's no reason for this test to be closed so I am moving it to open as well.
