Array deserializing issue/needs update from libgdx?

[ghost]

It looks like this project is out of date compared to the libgdx version. The following bug occurs when using this code but does not occur with the libgdx version. (See class comment for bug description.)

//import com.badlogic.gdx.utils.Json;
import com.esotericsoftware.jsonbeans.Json;

/**
 * Bug: Deserializing an array of objects with length other than 1
 * fails in some cases. The deserializer creates an array whose length
 * is based on jsonData.size, but this value is 1 (see Json.java:851).
 * It then tries to populate the array with the correct number of objects
 * by iterating over the children. This results in an
 * ArrayIndexOutOfBoundsException after the first child since the array
 * has the wrong length.

Hey. I'm not opening a new issue as I'm not having any problems with the current version but are you planning on keep updating this lib? I use it extensively on my Android apps.

I use it in my projects as well, so yes, I will continue maintaining it. It hasn't needed any new features for quite some time.

FWIW, JsonValue also isn't the most efficient way of doing it, though it is an easy to use API (which was the goal). Using JsonReader and overriding the protected methods enables streaming JSON parsing.

Cool thanks for letting me know
