[antlr-interest] Newbie trying to tame lexer

[forumer at smartmobili.com]

Thanks a lot, I just see your answer now and I am trying it.
It seems to work except for javadoc comment :

/**
public class FooBar extends Bar {

}
*/

I get a new FailedPredicateException(input, "BLOCK_COMMENT", 
"input.LA(1) != '*' && input.LA(2) != '/'");
