Test change look okay but it will need a CSR and RN to track the behavior change. Also test/jdk/java/nio/file/WatchService/SensitivityModifier.java will need attention - maybe it should just be replaced with a sanity test that ensures that the register method does not throw when called with one of these modifiers.
