Still one small mistake I missed in my previous review - sorry
about that.

For the new tests under jdk/net/ExtendedSocketOption/ these are
testng tests. They should be throwing `org.testng.SkipException`
not `jtreg.SkippedException` in their @BeforeTest method, that
is what the testng machinery expects.

   - import jtreg.SkippedException;
   + import org.testng.SkippedException;

...

   - throw new SkippedException("NAPI ID not supported on this system");
   + throw new SkipException("NAPI ID not supported on this system");

best regards,
