my copy of java 8 on os x has javax package.

my copy of java 8 on debian/ubuntu (linux mint) not.

exception in thread "main" java.lang.noclassdeffounderror: javax/vecmath/point3f

how hold of portable version (jar) contains package , include if doesn't exist @ run time?

the problem isn't javax missing; on debian installation should have of libraries such swing , javax.crypto. missing java 3d, library not come every java installation. should able download java 3d api here, , have point3f , other classes in javax.vecmath.
