[jira] [Created] (JOHNZON-345) StackOverflow when serializing Collection

Markus Karg created JOHNZON-345:
-----------------------------------

             Summary: StackOverflow when serializing Collection<URL>
                 Key: JOHNZON-345
                 URL: https://issues.apache.org/jira/browse/JOHNZON-345
             Project: Johnzon
          Issue Type: Bug
          Components: JSON-B
    Affects Versions: 1.2.11
            Reporter: Markus Karg


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));}}
