Thanks, fixed as you suggested, minor change in DNSTestUtils to support it

Thank you for checking this, there is a platform specified known issue on macOS which caused PortUnreachable failure, but it’s unrelated to JNDI feature, and test working well on other platforms, so I add it to problemlist to exclude the test for macOS only, feel free to let me know if it’s not suitable, I could just remove the test here for now

Sure, changed as you suggested, thanks

If possible put some comment why we choose 1 second, this will help in debugging if this test fails intermittently in future.

Sorry, I forgot to refactor this test with testbase (actually, its not necessary too, but guess the consistent style and shared base/methods will make the test easy to read and maintain, refactored this test and PortUnreachable.java now)
