test/langtools/tools/javac/valhalla/lworld-values/ArrayCreationWithQuestion.java:27
    Indentation (tab vs space)
test/langtools/tools/javac/valhalla/lworld-values/CheckQuestionInMessages.java:13
    X.ref[] xa = new Object[10]; should it be X.ref[] xa = new Object.ref[10]; I'm sure it is correct (Object.ref doesn't
