[antlr-interest] Stop ASTWalker on own Exception

[Alexander Gängel]

I throw under some circumstances in an Action an exception.

Is it possible to stop the astwalker when the excetion occurs? In the 
book the example only works when an RecognitionException occurs.

The rule is like this:
rule: Identifier
    {
        ...owncode...
               if(error){
                    throw new OwnException();
                            }
        }
    ;
    catch [OwnException e]{
            System.err.println(e.toString());
    }


Thank you
Alexander
