Query does not return results after nested transaction committed

[ifedan]

Cannot get any results after nested transaction was executed.

Transaction outer = graph.tx();

//Try to find vertex that does not exist
//There is an index exists on propName
GraphTraversal<Vertex, Vertex> traversal = graph.traversal().V().has(label, propName, propValue);
if (traversal.hasNext()) {
        return;
}

//Add vertex in nested transaction
TitanTransaction inner = graph.newTransaction();
inner.addVertex(T.label, label, propName, propValue);
inner.commit();

boolean stored = graph.traversal().V().has(label, propName, propValue).hasNext();
if (!stored) {
      //ERROR: Can't get added vertex
}
stored = graph.traversal().V().has(label, propName, propValue).limit(1).hasNext();
assert stored != null;

outer.commit();

The problem exists because of an indexCache inside StandardTitanTx that cached previous result.
