This is a new test for the fix of
https://bugs.openjdk.java.net/browse/JDK-8146537

I find the test to fail at least on Windows 7.
It may be a test bug or perhaps the fix does not work properly
-------
Test can fail if the icon hides to a tray icons pool in Windows 7/10, which is behavior by default.
Set "Right mouse click" -> "Customize notification icons" -> "Always show all icons and notifications on the taskbar" true to avoid this problem. Or change behavior only for Java SE tray icon.
