Question:
Found multiple occurrences of org.json.JSONObject on the class path:
jar:file:/C:/Users/nmj/.m2/repository/com/vaadin/external/google/android-json/0.0.20131108.vaadin1/android-json-0.0.20131108.vaadin1.jar!/org/json/JSONObject.class
jar:file:/C:/Users/nmj/.m2/repository/org/json/json/20160810/json-20160810.jar!/org/json/JSONObject.class
You may wish to exclude one of them to ensure predictable runtime behavior
