-----------------------------------
Summary: Json.createObjectBuilder(Map) cannot handle non-scalar
types
Key: JOHNZON-225
URL: https://issues.apache.org/jira/browse/JOHNZON-225
Project: Johnzon
Issue Type: Bug
Affects Versions: 1.1.12
Reporter: Ivan Greene
Json.createObjectBuilder(Map<String, Object>) throws JsonException when passed
a Map who's values are non-scalar types (JsonValue subclasses such as
JsonArray/JsonObject are permitted, however).
An example:
{code:java}
@Test
public void shouldBuildJsonObjectFromMap() {
Map<String, Object> map = new HashMap<>();
map.put("foo", "bar");
map.put("baz", new HashMap<>());
map.put("quux", new ArrayList<>());
JsonObject build = Json.createObjectBuilder(map).build();
assertThat(build.getJsonObject("baz")).isNotNull();
}
{code}
This results in the exception "javax.json.JsonException: Illegal JSON type!
name=quux type=class java.util.ArrayList"
This is not a problem in Yasson. The spec mentions that
IllegalArgumentException should be thrown if a value from the map cannot be
converted to the corresponding JsonValue, but in this case Maps or Lists should
be converted to JsonObject or JsonArray
