Description

The following groovy file:

public class bug8 {
bug8()

{ def x = null x + 3 }

static void main(String[] args)

{ def b = new bug8() }

}

Produces:

Caught: java.lang.NullPointerException: Cannot invoke method plus() on null object

Without a line number for the exception, it's hard to pinpoint it. When called from Java, I get the following error message:

Exception in thread "main" java.lang.NullPointerException: Cannot invoke method plus() on null object

The "Unknown Source" is the issue here.
