What? I'm just saying that currently valueMap returns `Map<String,Object>`,
so if you iterate on all the keys as String, you get a runtime crash because
there are keys that are not strings. So if you don't want to put only String as
keys, you need to change the Map to `Map<Object,Object>` , which will also
break existing code.
> PropertyMapStep returns Map<String,E> but puts non String keys in it!

> Project: TinkerPop
> Issue Type: Bug
> Components: process
> Affects Versions: 3.2.2
> Reporter: JP Moresmau
>
> PropertyMapStep.map has return type Map<String,E>, but if includeTokens is
> true:
> {code}
> if (element instanceof VertexProperty) {
> map.put(T.id, element.id());
> map.put(T.key, ((VertexProperty) element).key());
> map.put(T.value, ((VertexProperty) element).value());
> } else {
> map.put(T.id, element.id());
> map.put(T.label, element.label());
> }
> {code}
> T.id, T.key and T.value are NOT strings, so code looping through the keys in
> Java fails. toString() are missing... But do we rely on having these keys in
> other operations?
