JDK 9 on Windows copy-paste:
— begin —
$ cat JDK8066943.java
package scratch;
import java.nio.file.Paths;
public class JDK8066943 {
public static void main(String[] args) throws Throwable {
System.out.println(Paths.get("..").relativize(Paths.get("x")));
System.out.println(Paths.get("").relativize(Paths.get("x")));
}
}
$ ./build/windows-x86_64-normal-server-release/jdk/bin/java -cp . scratch.JDK8066943
..\x
x
— end —
So the issue description is accurate and an IAW should be thrown for that case, but the behavior in Max’s comment is no longer reproducible so a new, separate issue does not need to be filed for it.
Thanks,
Brian
