[antlr-interest] Should a Lexer barf on any input file?

I added a driver loop similar to that below to my under-development
Lexer to be able to test it as I go.
while ( !done ) {
Token t = lexer.nextToken();
PrintLine("Token: "+t);
}
My query is this: is it possible for the Lexer to barf on a file that
the combined Parser/Lexer would accept?
Basically, I'm trying to determine if it is possible for the Lexer
alone to reject a file that the Parser/Lexer combo accepts.
Cheers,
Micheal
