    [ https://issues.apache.org/jira/browse/JOHNZON-193?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16663565#comment-16663565 ] 

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}
