JRELoadError

Mon Feb 2 16:44:23 UTC 2015

What version of the javafxpackager? Try using the latest in the 8u40 EA builds if you haven't already. You should still be able to bundle Java 7 with it if your app doesn't run with 8.

We are actively discouraging developers from using Apples Java SE 6, since it has been deprecated for almost 5 years, and will be unavailable for some future version of OS X. We want developers and users using the best/newest Java available, even if Apple's old one is installed.
