It's an inconvenience which can be overcome by compiling the test and `SkippedException` together:


javac -d ./build -cp ./build \
        test/lib/jtreg/SkippedException.java \
        test/jdk/javax/swing/JPopupMenu/NestedFocusablePopupTest.java
java -cp ./build NestedFocusablePopupTest


The advantage is that the test will be reported as skipped if it isn't run when not in Wayland session. It could be not issue as more and more systems use Wayland session by default.
