[antlr-interest] Bad Token-type to AST-Class map in 2.7.2 Java; broken release

[Ric Klaren]

Hi Terence,

You've seen this one ?

Thomas a question: where do you have these token sections? lexer or parser?
Parser and lexer in one file or multiple, token section with the lexer or
with the parser ? A small example grammar would be practical.

Don't think I will fix it for 2.7.3 in C++ mode it touches too many icky
parts. (Although in C++ mode it's probably something else going wrong as in
Java mode)
