[antlr-interest] IndexOutOfBoundsException

[Gerz, Michael]

Hi Terence,

with the latest ANTLR snapshot, we get the exception below. (The bug may not be specific to this snapshot.)

Do you need the corresponding tree grammar? We would have to remove some code before sending it to you.

Best regards,

Michael
