I'll change it to a primitive short. It's a short to match the loop counters used elsewhere e.g. https://github.com/GCHQResearcher1337/tinkerpop/blob/a80eb84169048ed74c5ad27ebc4d12944fd0136a/gremlin-core/src/main/java/org/apache/tinkerpop/gremlin/process/traversal/traverser/B_O_S_SE_SL_Traverser.java#L34 But I originally used a Pair<> before switching to a class, which prevented me from using primitive types.
