Hello there,

we are using JOGL 2.0-rc3 in one of our projects. Lately a client told us that our program won't start on his MacBook Air. The JVM shows the following stack trace/error message:

java.lang.ExceptionInInitializerError

The installed JVM version is 1.6.0_26. Anyone know how to fix this?

Thanks,
