I believe there is an easier solution. However, you don't provide a test
case so I don't know if it works.
CHANGE:
```
@Override
public Edge addEdge(final String label, final Vertex inVertex,
final Object... keyValues) {
final Edge edge = this.addOutEdge(label, inVertex, keyValues);
if (inVertex.equals(this)) {
if(null == this.inEdges)
this.inEdges = new HashMap<>();
List<Edge> inE = this.inEdges.get(label);
if (null == inE) {
inE = new ArrayList<>();
this.inEdges.put(label, inE);
}
inE.add(edge);
}
return edge;
}
```
TO
```
@Override
public Edge addEdge(final String label, final Vertex inVertex,
final Object... keyValues) {
final Edge edge = this.addOutEdge(label, inVertex, keyValues);
if (inVertex.equals(this)) {
if (ElementHelper.getIdValue(keyValues).isPresent())
this.addInEdge(label, this, keyValues);
else {
final Object[] keyValuesWithId =
Arrays.copyOf(keyValues,keyValues.length+2);
keyValuesWithId[keyValuesWithId.length - 2] = T.id;
keyValuesWithId[keyValuesWithId.length - 1] = edge.id();
this.addInEdge(label, this, keyValuesWithId);
}
}
return edge;
}
```
Note that when I do this, all the current tests in TinkerPop pass
(`StarGraphTest`). Moreover, I added a test case to `StarGraphTest` that uses a
`GraphFilter`. I hope it tests what you want it to (when I didn't change the
method, the test still passes :| -- thus, you may need to add a test to ensure
we get failure without the new method addEdge method).

Finally, I think that you might think that bothE() would only return the
edge once, it shouldn't. It should return it twice. If that is the
misunderstanding, then this is NOT an issue.
```
gremlin> g.V(0l).bothE()
==>e[1][0-self->0]
==>e[1][0-self->0]
```
