Can't run packaged app on Mac OSX

Hello, I’m new to jME and game development.

I have been experimenting with some small samples and having a great time but, whenever I try to run a project as a packaged executable, it will crash with:

Exception Codes: KERN_PROTECTION_FAILURE at 0x00007fff9365eb28

The only post I found here that was related died without resolution:

When I run my samples from the IDE they run fine. When I run the .jar files in the dist/ directory they run fine; it’s only when I try to run the .app executable that things go awry.
