---------------------------------------

Potential Test Case:

{code}
class org.apache.jackrabbit.oak.security.authorization.permission.TreePermissionImplTest ....
...
    @Test
    public void testCanReadHiddenNode() throws Exception {
        // ensure that :index exists
        Tree adminIndex = root.getTree("/jcr:system/jcr:versionStorage/:index");
        assertTrue(adminIndex.exists());

        ContentSession session = createTestSession();
        Root root = session.getLatestRoot();
        Tree vs = root.getTree("/jcr:system/jcr:versionStorage");
        Tree index = vs.getChild(":index");
        assertTrue(index.exists());
        session.close();
    }
{code}
