[JAVA3D] Exception in RenderBin.removeDepthSort()

[Nikolai V. Chr.]

I tried running with:
view.setTransparencySortingPolicy(View.TRANSPARENCY_SORT_GEOMETRY);

But I encountered this exception: (not every time)

java.lang.NullPointerException
        at javax.media.j3d.RenderBin.removeDepthSort(RenderBin.java:6295)
        at javax.media.j3d.RenderBin.updateObject(RenderBin.java:836)
        at
javax.media.j3d.MasterControl.updateMirrorObjects(MasterControl.java:2633)
        at javax.media.j3d.MasterControl.runMonitor(MasterControl.java:3321)
        at javax.media.j3d.MasterControl.doWork(MasterControl.java:2890)
        at
javax.media.j3d.MasterControlThread.run(MasterControlThread.java:28)

Any ideas what can be causing this?

Regards
Nikolai
