Jar Files Not Launching: OSX 10.6.4

I've been having trouble with a couple jar files opening since I upgraded to Snow Leopard from Tiger. Both files are definitely working just fine. I used both of them previously on Tiger. There seems to be an issue with the application class. I'm running a Mac Pro Quad on OSX 10.6.4. I have Mandolane and the mmj's installed. I'm at a loss. Originally it was trying to open all of my HAL plugins at every launch. I've since moved those to remove a variable. I also tried downgrading to 10.6.3. It still didn't work and a few other things like iTunes and such went on the fritz. I quickly went back to 10.6.4. Any help would be greatly appreciated.

Here are the files and their console readouts if that helps. Both files are publicly available, I have just posted the direct links:

I tried opening the file in the Terminal as per an old post, but I only got the message:

Unable to access

Any ideas??? This ones eating my lunch. The 2 programs in questions, when working, make my workflow seamless. Without them there is massive amounts of mucking around and changing machines. Any help would be greatly appreciated.
