I have a java swing application which has been developed with netbeans 7.4 and jdk1.7.0_45.jdk. I'm using the native bundler to package that application with the mentioned JDK included. This works fine on a mac with OSX mavericks and also on windows 7. The packaged EXE starts fine in both environments.

I have a colleague which runs that program on mac os x yosemite and on windows 8.1. He has JRE and JDK 1.0.8_40 and 1.0.8_45 installed on both systems and when he starts that program the error JavaFX launcher error: Unable to invoke main method occurs.

How is that even possible if netbeans bundles everything fine inclusively the JDK 1.7? So it shouldn't matter if other environments have other JRE's or JDK's installed. I have no further information yet. As soon I have more info I will attach.

I also installed JRE and JDK 8 on my machine (os x mavericks) and the packaged applications still runs on my machine. So it seems not to use any Java 8 and it's usind the bundled JDK 1.7. This then would look like and OS version problem? Any ideas appreciated.

The application itself is a swing application just needing the FX launcher mechanism used to package applications in netbeans 7.4.
