[antlr-interest] How do I throw exception on ERROR "no viable alternative at character "

[Tilman Bender]

Hi,

Please have a look at the error reporting and recovery page on the wiki:

http://www.antlr.org/wiki/display/ANTLR3/Error+reporting+and+recovery

Maybe you could also override this:
http://www.antlr.org/api/Java/classorg_1_1antlr_1_1runtime_1_1_base_recognizer.html#6c32f5b03a9049357f3ddfbccee9a5e0

Allthough I am not sure this is a good idea.
