Hi Guntis,

I didn't see a reply to your email, but I'm seeing the same exception when
switching from antlr 3.0.1 to 3.1b1 (May 20, 2008). I tracked this down to
my lexer rules containing the '!' operator for example:

QUOTED_STRING
        :   (DQUOTE! (DSTRING_LETTER | STRING_NL)* DQUOTE!

I suspect my intent here was for the token text to not include the quotes
characters, but I already have a rule action to strip them off, so I think
my use of the '!' operator here is incorrect. Removing the '!' operator
eliminates the exception from ANTLR.
