No it isn't the right solution, it just picks the old version of Java3D (1.5) and use it with the "old" version of Java (Apple Java 1.6). It confirms what I wrote. Java3D 1.6 is compatible with Oracle Java 1.8. Your teacher is wrong, it is "the easy way" because as the Apple JVM will be abandoned, your program won't work in OS X versions with no Apple JVM.

Edit.: If you post this kind of "solution" on StackOverflow, I will downvote it because it will only confuse other developers. The right solution consists in knowing what you install on your machine, uninstall the old version of Java3D and then install the new version of Java3D.
