Reinhard Sandtner commented on JOHNZON-193:
-------------------------------------------
[~danielsoro] imo this is correct according the java doc of object builder
{code:java}
/**
* Add the given String value to the JsonObject to be created.
* If a value with that name already exists it will be replaced by the new
value.
* @param name the JSON attribute name
* @param value the String value to add
* @return the current JsonObjectBuilder
*/
{code}
it is not specified if the {{JsonObjectBuilder}} can be reused or not and
johnzon doesn't clear the builder so you can not reuse it.
for your usecase the following code should work
{code:java}
JsonArrayBuilder builder = Json.createArrayBuilder();
IntStream.range(1, 10)
.forEach(i ->
builder.add(Json.createObjectBuilder().add("key", String.format("Key %d",
i)).add("value", String.format("Value %d", i))));
{code}
> Johnzon is keeping the reference for map/values from JsonObjectBuilder.
