We have a couple JavaFX system tests that use AWT Robot, and fail when run on XWayland (due to JDK-8335468). This is tracked by JDK-8335470. These failing tests should be skipped until JDK-8335470 is fixed.

The failing tests are in:

tests/system/src/test/java/test/robot/javafx/embed/swing/SwingNodeJDialogTest.java
tests/system/src/test/java/test/robot/javafx/scene/SRGBTest.java

As part of this, the isOnWayland method that was added to SwingNodeBase should be moved to "tests/system/src/test/java/test/util/Util.java". That method should also check PlatformUtil::isLinux (we don't need to check the env var on macOS or Windows).
