The difference is all in the wrapping though.

$ type P.java
import java.nio.file.Files;
import java.nio.file.Paths;

public class P {
     public static void main(String[] args) throws Exception {
         Files.lines(Paths.get("login.com"))
              .filter(line -> line.contains("java"))
              .map(line -> line.substring(2, 13))
              .forEach(System.out::println);
     }
}
$ type s.groovy
import java.nio.file.*

Files.lines(Paths.get("login.com"))
      .filter(line -> line.contains("java"))
      .map(line -> line[2..12])
      .forEach(System.out::println)
$ javac P.java
$ java P
...
$ groovy s.groovy
...

(I don't even have groovysh defined on VMS, so no easy way to try -e)
