Well yes, Java is a little bit annoying when it comes to configuration. I think I will have to write some binaries that launch the tools and do the configuration part automatically.

So I tried the suggestions in the other post, but I still can’t get it to work. Now it complains about being OutOfMemory. While my swf is rather complex I’d imagine, I don’t think it’d warrant being out of memory when I have 1.5GB+ free memory. Is there some Java setting I must change in order to get this working?

I am indeed running this on a Mac and I’ll give this a shot to see if I can get it running!

Hey Joa! This looks mighty interesting, but I can’t get it to work. I get the following exception:
