> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 7.7.0
> Environment: Windows 8.1 64-bit, JDK8_121, Wicket 7.7.0, Jetty 9 / WebSphere 9
> Reporter: David Rain
> Assignee: Martin Grigorov
> Labels: json, open-json

>
> If we have an Object (POJO) that includes array(s), it fails on java.lang.NullPointerException when I pass it as an argument to the JSONObject constructor.
> The cause is that JSONArray cannot be included in tje JSONObject anymore because of absence of some readMethods (it fails on NPE at line 234 in JSONObject). I assume this is caused by switching to open-json.
> Simpliest example:
> {code:java}
> public static void main(final String[] args) {
> final JSONArray array = new JSONArray(new Object[] { 1, 2, 3 });
> new JSONObject(array);
> }
> {code}
> fails on:
> {noformat}
> Exception in thread "main" java.lang.NullPointerException
> at org.apache.wicket.ajax.json.JSONObject.propertiesAsMap(JSONObject.java:234)
> at org.apache.wicket.ajax.json.JSONObject.<init>(JSONObject.java:225)
> at cz.kb.dcs.module_frontend_base.components.graph.renderer.GraphRendererJSONUtils.main(GraphRendererJSONUtils.java:53)
> {noformat}
