Ref https://github.com/sbt/ivy/pull/26 Ref sbt/launcher#38 JDK 9 complains when java.lang.reflect.Field#setAccessible is called. So on JDK 9 to get the default Authenticator on JDK you can just call Authenticator.getDefault(). However ivy targets JDK 6.. So on JDK < 9 we do what we've always done, and on JDK 9+ we use java reflection to call Authenticator.getDefault(), which is public and doesn't require setAccessible(true).
