[antlr-interest] ArrayIndexOutOfBoundsException while generating code in v3

[John Goering]

Hi there,
Thanks, here's the grammar (as far as I got when I noticed I could generate
code with it). Please note that I'm still extremely wet behind the ears in
regards to the whole thing. ;)

Thanks in advance for any help...
