A java.util.List is defined at the start of the rule and
all Identifier-tokens are added to it.
Token id=null;
List list_id=null; *// <- !!!*
try {
// Test.g:17:3: (id+= Identifier ( ',' id+= Identifier )* )
// Test.g:17:6: id+= Identifier ( ',' id+= Identifier )*
{
id=(Token)match(input,Identifier,FOLLOW_Identifier_in_ids80);
if (list_id==null) list_id=new ArrayList(); *// <- !!!*
list_id.add(id); *// <- !!!*
...
