[antlr-interest] Bug? "new (new" code generated.

[Mark Volkmann]

I think I ran into this same problem. I believe the following is a
true statement.

If your lexer grammar and parser grammar are in separate files then in
order to debug the parser grammar using ANTLRWorks, you have to use
remote debugging.

Here are the steps that work for me.

1) Modify your build script (I use Ant) to include the -debug option
when running org.antlr.Tool.
2) ant clean run (where the run target runs your application that uses
the generated classes)
3) start ANTLRWorks
4) open the parser grammar file
5) select Debugger ... Debug Remote...
6) press "Connect" button
7) use the debugger as usual

I added a wiki entry on this at
http://www.antlr.org/wiki/pages/viewpage.action?pageId=5832732.
