I think it's great that you reduced a 200+ line program into a 9 line 
simple case.  that's always a good idea, and frequently it helps you 
solve your own problem, reducing it for public comment.

But the other requirement is that you actually test that the code you 
show produces the error you show.  It does not, probably because those 
strings in the literals are not exactly what you had in the original.
