[antlr-interest] DOT missing in java.g example

[ronald.petty at milliman.com]

Hi,
I was looking some more over the java.g grammar and noticed that DOT=. is 
commented out in the Lexer.  However I don't see a Token or Literal 
representation for DOT except for


// a numeric literal
NUM_INT
        {boolean isDecimal=false; Token t=null;}
    :   '.' {_ttype = DOT;}
            (   ('0'..'9')+ (EXPONENT)? (f1:FLOAT_SUFFIX {
                {
                                if (t != null && t.getText
                        _ttype = NUM_FLOAT;
                                }

How does this work for class.method if you have never seen a NUM_INT yet 
to add a '.' or DOT="." to the literals?

Thanks
Ron
