Summary: interactive recursive method def/calls fail

Initial Comment:
ONe used to be able to write recursive method
definitions in the interactions pane, and then
call those methods.   
  Try a simple recursive method def
   int sum(int n) { 
      if (n == 0) 
         return 0;
      else 
         return n + sum(n-1); 
   }

Now call  sum(0)  or sum(1)  or sum(2)  or sum(5) 
They fail with different error messages: mostly 
Bad type in substraction or NullPointer Exception.
Even sum(0) fails!  with a Bad Type in subtraction
error.  
   What exactly is the interactions pane doing if
it cannot evaluate such a simple method call?
