[antlr-interest] Antlrworks freezes

[Andreas Meyer]

Hi!

When opening my (big) grammar in AntlrWorks, I usually tell java to use 
as much memory as possible, such as (from commandline)

$ java -Xmx1g -jar antlrworks.jar

Maybe the different look&feel implementations have different memory 
usage patterns, so one look&feel runs out of memory earlier  than the 
other ...
