I ran the test as root and as my normal user. For the normal user one gets

STARTED    TargetDirectory::testReadOnlyDirectory 'testReadOnlyDirectory()'

whereas for root

SKIPPED    TargetDirectory::testReadOnlyDirectory 'testReadOnlyDirectory()' @DisabledIf("jdk.test.lib.Platform#isRoot") evaluated to true

which looked okay to me.
