If run this test without jtreg option '-nativepath', jtreg will report 'JUnit test failure'. After this PR, we add jtreg directive `/native` to test header, run this test without jtreg option '-nativepath', jtreg will report 'Error. Use -nativepath to specify the location of native code'. So add `/native` directive will make this test more friendly.
