Im getting this runtime error when colliding my avatar (maze3d style)  with a simple cube:

I dont think that the error is in the definition of the collider node, i have done before with simple planes and dont had any problem:

Shape3D s3 = new Shape3D();
        GeometryArray ga =(GeometryArray) TestUtils.createCubeViaTriangles(0f, 6f, 0f, 12f, false,true);
        TestUtils.reverseWinding(ga);
        s3.setGeometry(ga);
        ColliderGeometry cg = new ColliderGeometry();
        cg.setModel(s3);
        BiTreeCollider bic = new BiTreeCollider();
        bic.build(cg);
        ColliderNode cnode = new ColliderNode(s3,ColliderNode.CT_GEOMETRY,ColliderNode.CT_GEOMETRY,false,bic);
        cs.addCollider(cnode);
      scene.addChild(s3);



Anyone can bring some light to the problem? Thanks  :-/
