[antlr-interest] ANTLRWork freez

[Robin Davies]

I had a freeze in ANtlrWorks that went away when I increased the available 
memory for the Java VM:

   C:\Windows\System32\java.exe -Xmx1500000000 -jar 
C:\Users\Robin\antlrworks-1.0.2.jar

Maybe try that.

Probally recursive rules, in some cases, freez ANTLRW.

I don't know if Jean can use the attached grammar to test some of my
problems using ANTLRW.

Thanks to all.
