wso2esb json с управляющими символами (например, \ u000b = вертикальная табуляция = табуляция строк)

При публикации действительного документа json, содержащего управляющие символы, в API wso2esb 5.0.0, я получаю следующее исключение. Я использую JsonBuilder.

Пример JSON: 

{ "message": "hello\u000bworld" }

Исключение:

Последовательность передачи не выполнена. Как я могу избежать исключения и обработать этот документ json, как и другие документы json?
