[antlr-interest] Antlrworks1.4.3 can't debug/interpret/check grammar

[Seref Arikan]

Greetings,
My system is using Win 7 64 bit, I start antlr with
java -Xmx4G -jar antlrworks-1.4.3.jar and antlr options under preferences
has -Xmx10G
The system has 16GB ram, and I'm trying to see how sql 2003 grammar
(available from the antlr grammars on the web site) handles various things.

Trying to invoke debug grammar, or interpret, or check grammar gives an
error on the command prompt, but it is so fast that I could not even see
the beginning of the message.
It keeps repeating
org.antlr.analysis.SemanticContext.and(SemanticContext.java:616 to the
console. I've seen this problem reported by one more thread without a
solution.

I've managed to produce the same situation yesterday with a much simpler
grammar.

Is there any way I can access an older version of antlrworks which may not
have this issue? It would take me a lot longer to figure things out without
antlrworks

Kind regards
Seref
