[antlr-interest] Antlr3 does not report error with incorrect input.

[Martin Fowler]

The "xitem foo" was deliberate - I wanted the error.

But the latter part of the message did the trick for me - thanks. I 
didn't realize I needed the EOF in the grammar, although now you mention 
it, it does make sense. I fixed the grammar, and now get `line 1:0 
mismatched input 'xitem' expecting EOF` - which is what I was looking for.
