Do they have the App bundle for mac? The one i made with the jar works perfectly. If they made it for mac, i think they are having problems with the latest update, for Mac os 7.5 or something. It renders java 7 as the default java for all macs who have the update. I used the Jar Bundler to avoid this issue so the extra steps to launch it as stated in this post. It just bundled up the jar with jave JRE 1.6+ or something, i would have to check to be sure.
The app bundle template is on the github page.
You just said
And no - you cant update it successfully without a new launcher.
That's what I'm talking about with it probably not working, though I'd have to juryrig my own version to test it out. Something I can't do right now.
Edit at 5:30 CST to avoid a doublepost ---
So I tried this after I got home. I pulled a fresh copy of the github files and only rolled the version number back. I then ran the maven build from inside eclipse, and got the app bundle.
I ran this, and got the update prompt. It actually updated correctly. The only thing "wrong" that it did was to run the jar directly instead of relaunching the app, but that was only noticeable because of the missing dock icon. It's closer, but could use some tweaking.
