I have a little problem

[MagFra]

Can you please help me sort this out?
I keep getting a error massage.

import org.json.JSONArray;
import org.json.JSONObject;

public class Main {

    public static void main(String[] args) {
        String jsonStr = "{ \"Number1\" : 123.456 , \"Number2\" : [ 223.456 , 323.456 ] }";
        JSONObject json = new JSONObject(jsonStr);
        Float number1 = json.getFloat("Number1");
        System.out.println(json);
        JSONArray jsonArr = json.getJSONArray("Number2");
        System.out.println(jsonArr);
        System.out.println(number1);
        Float number2 = jsonArr.getFloat(0);
        System.out.println(number2);
        Float number3 = jsonArr.getFloat(1);
        System.out.println(number3);
    }
}

Please post the errors you are seeing. Your code compiles and executes correctly for me.

Hmm... Ok...
This simple program was created to illustrate a problem I got in a much bigger project I'm been working on, on and off for some time. The problem occurred when I, after taking a long pause, got back to it the other day. Immediately the IntelliJ IDEA goes in to update all sorts of things. (Both it self, plug inns and project dependencies. (I use Maven to handle dependencies.))
Now the simple example here does show the exact same problem. So I will supply the entire console response and my Pom file.

Console:

Not sure. What Java version are you using?

[MagFra]

openjdk-14 java version "14.0.1"
SDK default (14 - Switch expressions)

[MagFra]

I am thinking I might switch to a later version, sort of soon-ich. I would like to evaluate the impact first.

Presuming this issue to be resolved since no activity has been logged recently. But feel free to post here if there are still problems.

[johnjaylward]

Users version: org.json 20210307 (2021-03-07) - LATEST
Fixed in 2021-04-27

@stleary , it looks like we need a new release published.
