I'm testing Tinkerpop frames. I have a relationship similar to Person Knows Person but everytime I test my code it gives me this error

I'm using OrientDb as the graph provider. What could have possible gone wrong?
Here is my code:
public interface Ingredient extends VertexFrame{
@Property("name")
public String getName();
@Property("name")
public void setName(String name);
@Adjacency(label="usedwith", direction=Direction.BOTH)
public Iterable<Ingredient> getUsedWithIngredient();
@Adjacency(label = "usedwith")
public Ingredient addUsedWithNewIngredient();
@Incidence(label = "usedwith")
public UsedWithEdge addUsedWithIngredient(final Ingredient person);
@Adjacency(label = "usedwith")
public void removeUsedWithIngredient(final Ingredient person);
@Incidence(label = "usedwith")
public void removeUsedWith(final UsedWithEdge usedWith);
}
public interface UsedWithEdge extends EdgeFrame {
@Property("weight")
public void setWeight(int weight);
@Property("weight")
public int getWeight();
@OutVertex
Ingredient getOutIngredient();
@InVertex
Ingredient getInIngredient();
}
and this is a snippet of the test case
Ingredient v1=framedGraph.addVertex(null, Ingredient.class);
Ingredient v2=framedGraph.addVertex(null, Ingredient.class);
v1.setName("cumin");
v1.setConservAndStoring("conservation yearly");
v1.setPrepAndUse("prep prep ");
v2.setName("cinnamon");
v2.setAbout("about is about");
v2.setConservAndStoring("conservation is daily");
UsedWithEdge edge=v2.addUsedWithIngredient(v2);
edge.setWeight((1)); // << error is thrown here !!
framedGraph.getBaseGraph().commit();
This is an OrientDb problem. I used
OrientGraphNoTx
and it worked pretty well.
