Hello,
I downloaded today the ANTLRWORKS-1.4.1 package (antlrworks-1.4.1.jar).
I started the jar file with
java -jar ../Downloads/antlrworks-1.4.1.jar
When I use the sample expr grammar found on antlr site, the debugger
stops working a few steps after the beginning with java null pointer
exceptions on the console screen:
[---- CONSOLE OUTPUT

Checking Grammar expr.g...

unsafe operations.

I have the same result with another grammar I downloaded from the site.
Any idea ?
Thanks for your help
