Can't get lambda forest to work

[Andrew Haley]

This is rev 179:d923ba684bc4 of http://hg.openjdk.java.net/lambda/lambda

It doesn't seem to work.  I compile

public class Closures 
{
  public static void main(String[] args) 
  {
    #int() fortyTwo = #()(42);

    System.out.println("Hello, World!" + fortyTwo.());
  }
}

but it doesn't run:

Any ideas what might be going wrong, please?

Thanks,
