[antlr-interest] Parsing Parts of Java Code

[Matthias Gutheil]

Hi,

am I'm right, that the filter=true option for the lexer doesn't help me 
with this grammer?

http://www.antlr.org/grammar/1090713067533/index.html

And in the Recognizer I can't use the filter flag ( I get an error 
message when using the antlr.Tool).
