public static com.jme3.math.Quaternion convert(javax.vecmath.Quat4f oldQuat) {
        com.jme3.math.Quaternion newQuat = new com.jme3.math.Quaternion();
        convert(oldQuat, newQuat);
        return newQuat;
    }
Nice convenience methods for conversion between javax.vecmath and com.jme3.math
Objects, also some jme to jbullet mesh conversion.
