Below is a smattering of what I get trying to launch "briss-0.0.11.jar" from the Finder (from Desktop, within its original folder). The unzipped folder contains a handful of JAR applications, and surprisingly, the actual BRISS application is only 28k. JPEDAL does open as a Java application, but that's all from the folder. I've confirmed this on two different computers, both in and out of "safe mode" in addition to downloading older versions of BRISS to the same avail. These are stock OS X machines. Simply downloading, unzipping and opening briss-0.0.11.jar results in a "non-launch". If it's been tested on OS X (and I've tried on Leopard and Tiger, 10.4/5), I'm obviously doing something wrong launching the sucker...
I'm super-excited about BRISS and I really want to try it!
Thanks for the detective work.
