ANTLRWorks on the Mac

[Yang Jiang]

Hi Mathias,

I'm not a Mac user:) but I looked at the code generated by my version of 
ANTLRWorks(1.2.1)
It's like this :

public class JavaParser extends DebugParser {

So, my guess is you have an old version of ANTLRWorks or ANTLR library 
in your class path.
You can try to start from command line lwith something like this
java -cp antlrworks.jar  -Xmx512m org.antlr.works.IDE

Hope this will work.
