From 174b71c017b4456d7bbadd10c0a4e0358e7145c6 Mon Sep 17 00:00:00 2001 From: Ovidiu Popa Date: Fri, 27 Nov 2020 09:10:54 +0200 Subject: [PATCH] OidcIdToken cannot be serialized to JSON if token contains claim of type JSONArray or JSONObject ObjectToListStringConverter and ObjectToMapStringObjectConverter were checking if the source object is of type List or Map and if the first element or key is a String. If we have a JSONArray containing Strings the above check will pass, meaning that a JSONArray will be returned which is not serializable (same applies to JSONObject) With this change, even if the check is passing a new List or Map will be returned.
