             Summary: JsonWriter.write(JsonValue) fails with simple values (strings, numbers, booleans)
                 Key: JOHNZON-195
                 URL: https://issues.apache.org/jira/browse/JOHNZON-195
             Project: Johnzon
          Issue Type: Bug
          Components: Core
    Affects Versions: 1.1.10
            Reporter: Bernd Gutjahr
         Attachments: johnzon-writer.diff

The following code snipped fails with a JsonGenerationException("Invalid json").

{{ try (JsonWriter jsonWriter = Json.createWriter(System.out))}}
{{ {}}
{{   jsonWriter.write(Json.createValue("hello"));}}
{{ }}}

I would have expected this code to write just the value to the output stream, e.g. "hello" in the above example. Reading such values via JsonReader.readValue() works fine and I wanted to write out any kind of values that have been read before.

As a workaround, I'm currently using the JsonWriter only for types ARRAY and OBJECT and otherwise just use JsonValue.toString(), but I want to get rid of such ugly code.

To fix the issue, I would suggest to take my attached patch (johnzon-writer.diff), where
I have enhanced the unit test JsonWriterImplTest to cover all kinds of values and then made some changes to JsonGeneratorImpl to get the test working.
