Serializing a map doesn't use serializers

[dAti-zz]

When I have a map with a Date object it isn't serialized according to serializers and configuration eg

        Ghost ghost = new Ghost();
        ghost.setDateTime(LocalDateTime.now());

        Map<String, Object> properties = new HashMap<>();
        ghost.setProperties(properties);
        properties.put("testtest", LocalDateTime.now());

        JsonbConfig config = new JsonbConfig()
                .withDateFormat("yyyy", Locale.ENGLISH);

        Jsonb jsonb = JsonbBuilder.create(config);

        String json = jsonb.toJson(ghost);

        System.out.println(json);
        Pattern pattern = Pattern.compile("\\d+:\\d+:\\d+");
        Matcher hoursMatcher = pattern.matcher(json);
        Assert.assertFalse("Should not contain hours", hoursMatcher.find());

Returns this json:

{"dateTime":"2017","properties":{"testtest":"2017-09-11T15:44:34.979"}}

The first date is okay but the second one is not using the configured format ("yyyy").

You can find a working example here:

Any idea when this will be released?
