[antlr-interest] BUG - Antlr does not ignore whitespace in calls to parameterized rules (Java output)

[Austin Hastings]

This grammar has a parameterized rule, "param[]":

grammar bug;
file: ID param[ $ID.text ] ;
param[String s] : WS ;
ID: 'a';
WS: ' ';


Because of the spaces inside the [ $ID.text ] in the "file" rule, the 
output java looks like this:

        try {
            // bug.g:3:5: ( ID param[ $ID.text ] )
            // bug.g:4:2: ID param[ $ID.text ]
            {
            ID1=(Token)input.LT(1);
            match(input,ID,FOLLOW_ID_in_file10);
            pushFollow(FOLLOW_param_in_file12);
            param( , ID1.getText(),  );
            _fsp--;

Note the invalid commas in the call to param( , ID1.getText(), )

If I change the "file" rule to eliminate the spaces:      file: ID 
param[$ID.text] ;

I get this generated java:

        try {
            // bug.g:3:5: ( ID param[$ID.text] )
            // bug.g:4:2: ID param[$ID.text]
            {
            ID1=(Token)input.LT(1);
            match(input,ID,FOLLOW_ID_in_file10);
            pushFollow(FOLLOW_param_in_file12);
            param(ID1.getText());
            _fsp--;

And the call to param is syntactically valid. I don't know enough about 
the innards to know if this is a template problem or a core problem.
