Romain Manni-Bucau commented on JOHNZON-345:
--------------------------------------------
[~mkarg] we still need the 3 days vote but was awaiting for some validation
from [~struberg] before launching this one. Mark if you can just quickly have a
look I can handle the release.
> 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
> Priority: Blocker
> Fix For: 1.2.12
>
>
> 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!
