Confused by origin changing when loading objects

Here is a Cone I have made and exported to a Lightwave .obj file.

I then load the object into Java3D using the following code parts

import com.sun.j3d.loaders.objectfile.ObjectFile;

public static Scene loadWavefrontScene(String location) throws IOException {
	ObjectFile loader = new ObjectFile(ObjectFile.RESIZE); 
        return loader.load(new FileReader(location)); 

And I add the Scene object’s group to the main group using .getSceneGroup() and .addChild(group)

And then I rotate the object around the X axis.

The object seems to have had it’s origin changed. How can I load models and keep their origin in the original place?
