Carsten Ziegeler commented on SLING-4288:
-----------------------------------------
After a discussion with [~pulkagar] we found the problem: If there is a key
with null value in map along with any other valid key-value pairs, and if we
assign this map to a key in JSONObject, the toString method returns null.
This has been introduced by the refactoring of SLING-3786
> JSONObject.toString() returns null when having a value of type map with a
> null value

> Key: SLING-4288
> URL: https://issues.apache.org/jira/browse/SLING-4288
> Project: Sling
> Issue Type: Bug
> Components: Commons
> Affects Versions: Commons JSON 2.0.8
> Reporter: Pulkit Agarwal
> Assignee: Carsten Ziegeler
> Labels: JSON
> Fix For: Commons JSON 2.0.10
>
>
> I am having a test case where I have to place a map in a JSONObject. Below is
> the sample code for the same.
> @Test
> public void testSample() throws JSONException
> {
> HashMap<String,Object> map=new HashMap<String,Object>();
> map.put("abc", "123456");
> map.put("id", null);
> List<String> list=new ArrayList<String>();
> list.add("Admin");
> list.add("password");
> map.put("groups", list);
> JSONObject response=new JSONObject();
> response.put("key", map);
> System.out.println(response.get("key"));
> }
> Now when I execute the code keeping org.apache.sling.commons.json version
> 2.0.8 in the classpath then response.get("key")returns null where as in case
> of bundle version 2.0.6 its returns map.
> Please note this issue is reproducible when the map is an element of type
> list.
