Blocker Description
The JSON-B specification mandates that compliant implementations MUST support serialization of Collection and URL.
Unfortunately when serializing a Collection<URL> using Johnzon-Jsonb 1.2.11 an infinite loop happens, resulting in a StackOverflowException.
I have reproduced this complaint by the following code:
JsonbConfig jsonbConfig = new JsonbConfig();
Jsonb jsonb = JsonbBuilder.create(jsonbConfig);
URL url = new URL("http://www.apache.org");
Collection<URL> collection = Collections.singleton(url);
System.out.println("Jsonb collection: " + jsonb.toJson(collection));
The same problem occurs with Collection<URI>, too.
Collections in general work fine, i. e. the problem does not occur with e. g. Collection<UUID> or Collection<String>. Also single URL and URIs objects work fine, i. e. when not inside a collection!
