Is Java API being actively developed and updated?

We have a Java application that we want to integrate with Jira Software (to sync up Projects, Boards, Sprints, Issues etc.). I understand this can be done using:

  • REST API - but this means you have to parse the response JSON yourself.
  • Java API - this should give you some added benefits (such as not having to parse the JSON yourself)

First of all, is my thinking correct, in that using Java API will be a bit more advantageous?

If so, is the Java API library being actively worked on and updated by Atlassian? I would appreciate your responses to this.
