Duplicate JSON dependency

[jusabatier]

When running tests, they complains about duplicate org.json.JSONObject classes :

Found multiple occurrences of org.json.JSONObject on the class path:

jar:file:/home/jusabatier/.m2/repository/org/json/json/20211205/json-20211205.jar!/org/json/JSONObject.class jar:file:/home/jusabatier/.m2/repository/com/vaadin/external/google/android-json/0.0.20131108.vaadin1/android-json-0.0.20131108.vaadin1.jar!/org/json/JSONObject.class

You may wish to exclude one of them to ensure predictable runtime behavior

I think you should exclude one of them.

Could you please clarify how to reproduce the problem (where tests complains appears) ?

I have this running tests on a springboot web application that embed mapfih-print lib.

Generate a dependency tree, it appear that :
