It does not, but when the test does fail, it takes ages to fail.
(e.g. if we are missing some env variable which we are rely on to disable system tray support when it is [needed](https://bugs.openjdk.org/browse/JDK-8322750)).

The action listener should be triggered when we release the Button1, and there was no such release in this test.
And we didn't wait long enough after that anyway, so it might pass even if it fails.
