TreeTraversingParser#readValueAsTree returns whole tree instead of current node

If you create a TreeTraversingParser on a node, say on {"b": {"bValue" : 1}} and have classes like:

class A {
  B b;
}

@JsonDeserialize(using = B.Deserializer.class)
class B {
  static class Deserializer extends JsonDeserializer<Expression> {
    @Override
    public Expression deserialize(JsonParser p, DeserializationContext ctxt) throws IOException {
      JsonNode jsonNode = p.readValueAsTree();
    }
  }
}

then you would expect jsonNode to represent {"bValue" : 1}, but instead it is the whole original tree ({"b": {"bValue" : 1}}).

The method p.currentNode returns the correct value, but is protected.

Could TreeTraversingParser override readValueAsTree and return currentNode instead of the current behaviour?

(I’ve tried to extract this example from more complex code, but I think the essence is correct. I can produce a minimal test case if that would help repro this.)

@robinkanters lol. Sorry about that. Auto-completion fail for some reason. 😃
